Satellite found the strangest and amazing planets. The biggest satellites in the world

Of all the satellites of the solar system, you can allocate a few most unusual. They all have some interesting features that will be discussed below.

Ganymed - the largest satellite

Satellite of Jupiter Gamornad itself very much resembles the moon, but it is much more and is the largest satellite of the whole solar system. Another one of his feature is the presence of magnetic poles. Gamenad is a bit larger than Mercury and a little less than Mars, it could be taken for the planet, if he were also rotating around the sun.

Miranda is not the most attractive satellite

Uranium satellites do not differ in presentation. Very allocated from all these satellites satellite called Miranda. His name is beautiful, but the appearance is not very. However, if you consider the surface of Miranda more closely, there is the most diverse landscape in the solar system: the gigantic ridges alternate with deep plains, and some canyons are 12 times deeper than the famous Grand Canyon!

Callisto - champion in crater

Satellite of Jupiter Calisto immediately seems to be a dead planet, which has no sign of life. A lot of meteorites fell on this satellite and, accordingly, they all left behind the traces that are now presented in the form of crater on the satellite. This is the main distinguishing feature of Kalisto. It is located on it the largest crater from all planets and satellites of the solar system.

Dactyl - Satellite asteroid

Dactyl is a satellite, the main distinguishing feature of which is that it is the smallest of all satellites of the solar system. Its length is just 1.6 km, but it revolves around asteroid. Dactyl - this is a satellite Ida. According to the ancient Greek myth, I was called the Mountain, in which tiny creatures lived - launched.

Epimeus and Janus - Eternal Race

Two satellites of Saturn in the distant past were one of the whole, but after the split, they began to move almost one orbit, every four years, by changing places and a miracle avoiding the collision.

Epimetes and Janus

Entseladd-Kohllessets

Enseladd is one of Saturn's largest satellites. It drops on it and reflects almost all the sunlight, as a result of which it is considered the most reflecting object of the solar system. Encelades have geasers throwing water vapor and dust into open space. Scientists believe that precisely because of the volcanic activity of its companion, Saturn acquired a ring E, through which Encelade orbit.

Ring E and Encelad

Triton - satellite with unique volcanoes

Triton is the biggest satellite of Neptune. This satellite differs from others in that it revolves around the planet towards its opposite rotation around the sun. Triton has a large number of volcanoes that emit not lava, water and ammonia, which instantly freeze after that.

Triton

Europe - Satellite Ocean

Europe is a satellite of Jupiter, which has the most flat surface. This feature is associated with the fact that Europe is covered with the ocean, and there is a thin layer of ice on its surface. Continuously there is a huge amount of fluid - several times more than on Earth. Some researchers who are engaged in studying this satellite concluded that in the ocean of Europe there may be life.

Europe

IO - volcanic hell

On the satellite of Jupiter IO constantly there is volcanic activity. This is due to the nature of the planet Jupiter, as a result of which the satellite subsoil is susceptible to heating. There are more than 400 volcanoes on the surface, and the volcano formation occurs continuously, they can easily be seen by flying by. But for the same reason, craters are practically not noticeable on the surface of the IO, since they are filled with lava, which is eructed from volcanoes.

Titan - the best candidate for colonization

Saturn Saturn Titan is the most unpredictable and unique companion. It has long been proven that it has a denser atmosphere than on earth. The composition of which there is nitrogen, methane and other gases. For a long time it was unknown, which is hidden under these thick clouds of the satellite, and only after the device took pictures, it became clear that the rivers and lakes of the Meton and Titanium nature are located. It is assumed that there are also underground reservoirs in Titan that there is a low gravity to bring it the best candidate for colonization by earthlings.

Top layers of the Atmosphere of Titanium and South Pole Saturn

Some of these Luns still remain a mystery for astronomers, because there is still no man's foot everywhere, but somewhere quite possible the existence of living organisms! But what we know exactly, this is at least their size. In this list you will get acquainted with the 10 largest planetary satellites in our solar system.

10. Oberon, uranium satellite (medium diameter - 1523 kilometers)

Oberon, also known as Uranus IV, is the most remote from the center of uranium satellite, the second in size among other satellites of this planet and the ninth mass among all the well-known satellites of our solar system. Opened in 1787 by William Herschel (William Herschel), Oberon is named after the mythical king of the elves and fairies mentioned in the work of Shakespeare "Sleep in the Summer Night". Oberon orbit is partially outside the uranium magnetosphere.

9. Reya, Saturn's satellite (average diameter - 1529 kilometers)

Reia - the second largest satellite Saturn and the ninth satellite in the entire solar system. At the same time, this is the second smallest cosmic body in our solar system, yielding only asteroid and dwarf planet Ceres in this rating. This status was obtained for confirmed evidence that he had hydrostatic equilibrium. Opened in 1672 Giovanni Cassini.

8. Titania, uranium satellite (average diameter - 1578 kilometers)

This is the largest uranium moon and the eighth in size in the solar system. Opened in 1787 by William Herzhel, Titania was named after the goddess Fay from the comedy Shakespeare "Sleep in the Summer Night." Titania orbit is not beyond the limits of uranium magnetosphere.

7. Triton, Neptune satellite (medium diameter - 2707 kilometers)

Triton is the largest satellite of the planet Neptune, open on October 10, 1846 by English Astronomer William Lassell. In our solar system, this is the only big moon with a retrograde orbit. Triton moves towards the reverse rotation of its planet. For its 2707 kilometers of diameter, Triton is considered the seventh satellite in the solar system. There was a time when Triton was considered the planet-dwarf from the asteroid belt of the bed for similar with Pluto properties - retrogradity and composition.

6. Europe, Jupiter satellite (medium diameter - 3122 kilometers)

This is the smallest of Galilean satellites, rotating around Jupiter, and the sixth in the proximity of the location to its planet. It is also the sixth satellite in the solar system. Galileo Galileo opened Europe in 1610 and called this heavenly body in honor of the legendary mother of the Cretan King Minos and Loveman Zeus.

5. Moon, Earth satellite (average diameter - 3475 kilometers)

It is believed that our moon formed 4.5 billion years ago shortly after the formation of the Earth itself. There are several hypotheses about its origin. The most common among them states that the moon was formed from fragments after the collision of the Earth with the cosmic body, in size comparable to Mars.

4. IO, Jupiter satellite (average diameter - 3643 kilometers)

IO is the geologically active heavenly object in our solar system, and deserved this title for at least 400 existing volcanoes. The cause of such emergency activity is the heating of the satellite subsoil due to tidal friction caused by the gravitational effects of Jupiter and other Galilee satellites (Europe, Gamornad and Callisto).

3. Callisto, Jupiter satellite (medium diameter - 4821 kilometers)

Galileo Galileo opened Callisto, like some other satellites of Jupiter, in 1610. Possessing impressive sizes, this satellite is 99% of the Diameter of Mercury, but only a third of its mass. Callisto is the fourth Galilean satellite of Jupiter to remotely from the center of the planet, which has an orbital radius in 1883,000 kilometers.

2. Titan, Saturn's satellite (medium diameter - 5150 kilometers)

This is the sixth ellipsoid satellite Saturn. It is very often called a planet-like satellite, because the titanium diameter is 50% more than the diameter of our moon. In addition, it is 80% heavier than our Earth's satellite.

1. Ganymed, Jupiter satellite (average diameter - 5262 kilometers)

Ganamed equally consists of silicate breeds and abundant water. This is a fully differentiated celestial body rich in iron, with a liquid core and an outer ocean, in which there may be more water than throughout the land in the sum of all its oceans. The surface of the gamonded is characterized by two types of relief. Satellite's dark regions are saturated with collections from collisions with asteroids that occurred presumably 4 billion years ago. This relief shape covers about a third of the satellite.

Satellites are celestial bodies that turn around orbit around a certain object in outer space under the influence of gravity. Distinguish natural and artificial satellites.

Our space portal site offers you to familiarize yourself with the secrets of space, unthinkable paradoxes, exciting worldviews, providing in this section the facts about satellites, photos and video materials, hypothesis, theory, discoveries.

Among the astronomers there is an opinion that the satellite needs to be considered the object that rotates around the central body (asteroid, planets, a dwarf planet) so that the barycenter of the system, which includes this object and the central body, is located inside the central body. In the event that the barycenter is outside the central body, then this object cannot be considered a satellite, since this is a system component, which includes two or more planets (asteroids, dwarf planets). But the International Astronomical Union today has not yet given the exact definition of the satellite, arguing that it will be done in the near future. For example, Mas continues to be considered a satellite of Pluto Charon.

In addition to the above, there are other ways to determine the concept of "satellite", which you will learn about.

Satellites for satellites

It is believed that the satellites can also have their own satellites, but the torrential forces of the main object in most cases would have made this system extremely unstable. Scientists assumed the presence of satellites in Japite, Ri and the Moon, but today the natural satellites for satellites have not been identified.

Interesting facts about satellites

Among all the planets of the solar system of their own artificial satellite never had Neptune and Uranus. Satellites planets are small space bodies of the solar system that rotate around the planets by attraction. Today 34 satellites are known. Venus and Mercury, planets closest to the Sun, do not have natural satellites. The moon is the only satellite of the Earth.

Mars satellites - Dimos and Phobos are known for their small distance to the planet and relatively fast movement. Satellite Phobos goes twice during the Martian day and dates back. The Dimos moves slower: from the beginning of its sunrise, more than 2.5 days passes to the right. Both Mars satellites move almost exactly in its equator's plane. Thanks to spacecraft, it was found that Dimimos and Phobos in their orbital movement are irreversible and remain inverted to the planet only one side. Dimensions of Daimos are about 15 km, and the size of Phobos is about 27 km. Mars satellites consist of dark minerals and covered with numerous craters. One of them has a diameter of 5.3 km. Probably craters are born by meteorite bombardment, and the origin of parallel furrows to this day is unknown.

The density of phobos mass is approximately 2 g / cm 3. The angular velocity of Fobos movement is very large, it is able to overtake the axial rotation of the planet and, unlike other, the luminaries enter the east, and goes back in the West.

The most numerous is the system of satellites of Jupiter. Among the thirteen satellites, contacting Jupiter, four were opened by Galileem - this is Europe, Io, Callisto and Gamornad. Two of them are comparable in size with the moon, and the third and fourth exceed the dimensions of Mercury, although in weight they are significantly inferior to him. Unlike the remaining satellites, Galilean is more detailed investigated. In good atmospheric conditions, you can distinguish between satellite data and notice certain parts on the surface.

According to the results of observations of changes in the color and gloss of Galilean satellites, it has been established that each of them has a synchronous axial rotation with an orbital, so they are only one side addressed to Jupiter. Space devices "Voyager" removed the surface of the IO, on which the active volcanoes are clearly visible. A bright clouds of eruptions are raised above them, which are thrown into a large height. It was also noticed that there are reddish spots on the surface. Scientists suggest that these are salts who are evaporated from the bowels of the earth. The unusual feature of this satellite is the surrounding cloud of gases. The Pioneer-10 spacecraft provided data by which the ionosphere and the rarefied atmosphere of this satellite were opened.

Among the number of Galilean satellites, it is worth highlighting the Gamorn. It is the biggest among all satellites of the planets of the solar system. Its dimensions make up more than 5 thousand km. With "Pioneer-10" images of its surface were obtained. The picture is clearly visible spots and a bright polar hat. Based on the results of infrared observations, it is believed that the surface of the Ganamed, just like another satellite - Callisto, is covered with an innese or water ice. In Gamed, the traces of the atmosphere have been revealed.

All 4 satellites belong to the objects of the 5-6 star magnitude, they can be seen in any binoculars or telescope. Much weaker are the rest of the satellites. The closest satellite for planet is Amaltia, it is just 2.6 radius of the planet.

The remaining eight satellites are removed over long distances from Jupiter. Four of them rotate around the planet in the opposite direction. In 1975, an object was discovered by astronomers, which is the fourteenth satellite of Jupiter. Today, the orbit is unknown.

In addition to rings, which consist of a roa of numerous little bodies, ten satellites have been found in the Saturn planet system. This is Encelada, Mimas, Dion, The Afony, Titan, Ray, IPPE, Hyperion, Janus, Fea. The closest to the planet is Janus. He moves very close to the planet, it was possible to identify it exclusively at the eclipse of the rings of Saturn, who created a bright halo in the field of view of the telescope.

Titan is the largest satellite Saturn. By weight and sizes, this is one of the largest satellites in the solar system. Its diameter is about the same as the diameter of the car. It is surrounded by an atmosphere that consists of hydrogen and methane. Opaque clouds are continuously moving in it. Only the FEBA from all satellites rotates in the forward direction.

Uranium satellites - Ariel, Oberon, Miranda, Titania, Umbriel - rotate in orbits, whose planes almost coincide with each other. In general, the entire system is characterized by the original inclination - its plane is practically perpendicular to the average plane of all orbits. In addition to satellites, a huge amount of small particles move around uranium, which forms peculiar rings, not similar to the famous Saturn rings.

Planet Neptune has only two satellites. The first was opened in 1846, two weeks after the opening of the planet itself, and has the name Triton. By weight and sizes, he is more than the moon. It is distinguished by the backward direction of the orbital movement. The second is Neret - small, characterized by a strongly elongated orbital. Direct direction of orbital movement.

At Pluto, astrologers managed to detect the satellite in 1978. This discovery of scientists is of great importance, because it provides an opportunity to as accurately as possible to calculate the mass of Pluto on the data on the period of the satellite's appeal, and in connection with the discussion that Pluto is a "lost" satellite Neptune.

One of the key issues of modern cosmology is the origin of satellite systems, which in the future can open many secrets of space.

Captured satellites

Astronomers are not fully sure how satellites are formed, but there are many work theories. It is believed that most of the smaller satellites are captured asteroids. After the formation of the solar system in heavens, millions of space boulders wandered. Most of them were formed from materials that remained from the formation of the solar system. Perhaps others are remnants of planets, which massive space clashes were broken into pieces. The greater the number of small satellites, according to, it is more difficult to explain their occurrence. Many of them may appear in the Solar System region, such as the believer belt. This zone is located on the upper edge of the solar system and filled with thousands of planet-like objects of small sizes. Many astronomers believe that Planet Pluto and her satellite can actually be objects of the bouncy of the coipers, and they cannot be attributed to the planets.

Fate satellites

Phobos - Donet Mars Donet

Looking at the moon at night, it is difficult to imagine that it would not be. However, in the future, the moon may not really be. It turns out, satellites are not constant. Making measurements by laser rays, scientists found that the moon moves from our planet at a speed of about 2 inches per year. From this it follows: Millions of years ago, it was much closer than now. That is, when dinosaurs were still on Earth, the moon was closer several times as in our time. Many astronomers believe that one day the moon can escape from the gravity field of the Earth and go to space.

Neptune and Triton.

The rest of the satellites also came across such fate. For example, Phobos actually, on the contrary, is approaching the planet. And sometime he will finish his life, immersed in the atmosphere of Mars in fiery agony. Many other satellites can be collapsed under the influence of the tidal forces of the planets, around which they constantly rotate.

A lot of rings surrounding planets, consist of particles of stone and fire. They could form when the satellite was destroyed under the powers of the planet. These particles are located in thin rings over time, and you can see them today. The rest of the satellites next to the rings contribute to holding them from falling. The satellite gravity force holds particles from rollback back to the planet after breaking out of the orbit. In a circle of scientists they are called satellites-shepherds, as they help keep rings on the line, like sheep loses her sheep. If there were no satellites, Saturn's rings have already disappeared long ago.

Our portal site is one of the best space sites on the Internet. In this section on satellites, the most interesting, meaningful, informational, scientific and educational materials are collected.

Ganymed.

Let's start with the largest satellite of the solar system called Ganymed. It accompanies Jupiter and has dimensions exceeding the size of Pluto and Mercury. Therefore, if Ganymed had an orbit running around the Sun, he could become a full-fledged planet.

Despite the huge diameter of five thousand kilometers, the satellite has a density of just two times greater than the density of water. This suggests that by 50% this celestial body consists of water. It pursues on reflections about the inhabitancy of the satellite. There are huge crater from ice on the gamorn. These are places where water from the inner lakes is broken out and instantly frozen, forming the so-called "volcanoes".

Robert Pappalaro has long investigated the satellite and made the conclusion that in the area of \u200b\u200bthe equator, the surface of the Ganamed is similar to a porous sponge, and the bark is covered with "volcanoes". The internal pools formed should be warm enough, and this makes it possible to assume that there may be any form of life.

In addition, there are still some facts that may indicate that Ganymed may be inhabit. So, on the satellite there are active volcanic activity, which means the development of the planet. Gamenad is heated by emissions from Jupiter and has a huge hot core.

Ganymed has a magnetic field, thanks to which a beautiful aura is created, which is not a single satellite of the solar system. By the way, the presence of such a magnetic field also testifies to the health of the heavenly body.

Perhaps once a person will get to the Ganyada, and then much more facts about this mysterious satellite will be known, which is so similar to the planet.

Miranda

The satellite of Urania Miranda was awarded the title of the ugly satellite. It was opened on February 16, 1948 and became the smallest satellite of uranium out of five. With his name, he owes one of the characters of the play "Storm" W. Shakespeare. By the way, all previous satellites were also named after the characters of the works of this author.

Due to the huge remoteness from the Earth, just once, in 1986 it was possible to get a picture of Miranda. Studies have shown that the satellite has all geological forms that have been presented on solid solar system planets until that time.

Two theories are trying to explain this fact. One of them states that it is possible, the satellite faced with a huge celestial body, which literally destroyed him. However, under the influence of gravity, the satellite after a while "gathered" again. This was the cause of such a strange appearance.

Adherents of the second theory argue that Miranda's subsoil is unevenly warmed up, which leads to the fact that there is such a geological diversity on the satellite.

Satellite primer has large ice inclusions. In addition, astronomers concluded that some areas of Miranda changed their appearance at least five times. The territory of the satellite is completely covered with small crater. The exception is the area that received the name Chevron.

The satellite belongs to one of the highest formations among all satellites of the solar system - the rock of Verona RUPS. Its height is 20 kilometers. The unusualness is that this hill was able to form on the satellite, the dimensions of which are relatively small - only 472 kilometers in diameter. This fact may indirectly confirm the theory of the fact that the satellite was again assembled after the unsuccessful collision.

Callist

Satellite of Jupiter Callisto was opened in 1610 and his name he owes a friend of Zeus, turned into a bear. This is one of the oldest celestial bodies in the solar system. There is a huge number of crater on its surface, their quantity will not compare with any other space object that can be observed. This once again proves the ancient age of the satellite.

The thickness of the ice that covers Callisto is approximately 200 kilometers. At the same time, the thickness of the water layer under the ice is about 10 kilometers. Thus, the satellite Callisto is 60% consisting of water and ice. The remaining 40% compress the compressed rocks.

The main feature of the satellite is a huge bright spot that got the name of Valchalla. Its diameter is approximately 600 kilometers. Around this stain almost after the same intervals, the surface resembles a "plowed". Scientists explain this result of falling a huge amount of cosmic bodies.

Recently, a version was nominated that in Callisto, the surface of which is covered with ice, electrolysis processes can occur with the formation of an oxygen-hydrogen mixture. This mixture during accumulation in large quantities may become explosive. Once this connection will simply explode satellite and then his fragments will begin to fall on the ground. The blow of such a fragment can be equal to the atomic explosion, the power of which is a thousand megaton.

Dactyl

This is the smallest satellite in the solar system. However, he deserved fame. The fact is that the dactil is an asteroid satellite! It was discovered in 1993, when two asteroid flew towards Jupiter, one of which had a satellite. This asteroid was called Ida. Up to this point, scientists believed that asteroids could not have satellites. However, Dactyl proved the opposite. Currently, a few more speakers of asthids have been discovered.

On the picture on the left - the asteroid of Ida, on the right - the satellite dactyl.

Triton

This is the largest Neptene satellite, which was opened in 1846. The main oddity of this satellite is that it moves in the opposite direction from the movement of the planet. In addition, attracts the attention and orbit of triton, which makes it possible to develop the theory that once Triton was independently planet, which was attracted by the gravity of Neptune.

Due to the lack of solar heat, Triton is covered with ice of several shades. In places where nitrogen frozen is blue-green. Where it is contained by iron impurities it is reddish. The surface of the satellite is covered with cracks, which, by assumptions, appeared as a result of cryovulkanic activity. Triton has the most greatest seismic activity among all the heavenly objects studied. However, even it is absolutely unique here. Triton volcanoes spew ice, which is sprinkled by hundreds of kilometers.

Scientists believe that thanks to the nitrogen atmosphere, Triton can become suitable for life. However, it will happen in several billion years, when the sun becomes a red giant and hesitates the surface of the triton to the required temperature.

Europe

Sputter Jupiter Europe was opened in 1610. In size, it is similar to the moon, but its surface is completely covered with ice. Europe does not have any mountains, only small hills.

Europe has a huge gravitational attraction to the Jupiter, which affects the ice surface and causes the appearance of cracks. Inside the satellite is warm and possible on the bottom beaten geysers. This heat explains the presence of a huge ocean covered with ice. Astronomers suggest that its depth can reach a hundred kilometers.

In addition, it was proved that in a highly discharged atmosphere, in addition to oxygen on the satellite, there are carbon dioxide, which gives reason to think about the availability of life in the depths of the ocean.

Titanium

Perhaps the most mysterious satellite of the solar system. Titan, Saturna satellite, was opened in the 17th century. His mysteriousness lies in the fact that the dense atmosphere does not allow to look at the surface of the satellite, and the scientist remains only to guess what is hiding behind it.

On the surface of the titanium there are methane lakes. Scientists suggest that titanium is suitable for the life of the most primitive forms of life.

In size titanium a little more than Mercury. If he had a trajectory of movement around the Sun, it could be called the planet.

The solar land system consists of the sun and 9 planets. The planets of the solar system do not suffer from the inattention, therefore other no less important objects of the system remain without attention, such as satellites. But they are more interesting to their planets.
10. Ganymed - Large satellite

Ganymed can be confused with the moon, but there is a small difference in size. Ganymed is the largest satellite of Jupiter and in general the whole solar system. He is so huge that he has its own magnetic field.
9. Miranda - an ugly satellite

Miranda is considered an ugly dunchon of the solar system. At first glance it seems as if someone simply blinded satellite from pieces and sent him to rotate around uranium. Miranda has one of the most diverse landscapes in the entire solar system with its steep mountain ranges, valleys - crowns and canyons, some of which are 12 times deeper than a large canyon. If one is so throwing a stone, then it will reach the bottom only after 10 minutes.
8. Callisto - satellite with the largest number of crater

Callisto, satellite of Jupiter, just a pimpled teenager of the solar system. Unlike other celestial bodies of the same size, Callisto does not have geological activity that could protect its surface. Therefore, this satellite is the most "broken." Craters on it so much that they began to overlap one on one, forming whole rings inside other crater.
7. Dactyl - Satellite-Asteroid


Dactyl is the smallest satellite of the solar system, its width of the whole mile. The picture shows the asteroid Ida, and launched is just a small point on the right. Dratum still amazing object, because it rotates not around the planet, but around the asteroid. Previously, astronomers believed that asteroids were too small to have satellites. And here is not.
6. Epimeus and Janus - satellites, miraculously avoiding collisions


Epimetes and Janus - Saturn Satellites, who have almost one orbit, perhaps because they used to be one satellite. But what's the matter: every 4 years they change in places in almost a collision.
5. Encelada - Ring Carrier


Enceland is one of the main internal satellites of Saturn. It is also one of the objects reflecting almost 100% of the world. The Encelade surface is covered with geysers emitting into space of ice particles and dust, which are the source of the Ring E Saturn.
4. Triton - with ice volcanoes


Triton is the biggest satellite of Neptune. Also this is the only satellite of the solar system, rotating around its planet in the opposite direction of the planet itself. Triton is volcanically active. But if other volcanoes throw out Lava, volcanoes on the Triton mow water and ammonia, which freeze on the surface.
3. Europe - with big oceans


Europe, another satellite of Jupiter, has one of the most even surfaces in the solar system. All because the entire satellite is one solid ocean of water under the layer of ice. But this water exists only because of the tidal heating of Jupiter. In this ocean of water 2-3 times more than on Earth.
2. Io - volcanic hell


Because of the huge force of friction of Jupiter, volcanic activity constantly occurs on Io. This satellite resembles a mordor from the "Lord of the Rings". In fact, the entire surface of the IO is covered with volcanoes, and the eruptions happen so often that the "Voyage" was able to remove the process itself (red spots in the picture). There are no crater on Io, since Lava fills them and lines the surface of the satellite.
2. Titan - house away from home


Titan is the strangest satellite of the solar system. He has the only one there is a dense atmosphere (more dense than on earth), and what lies under opaque clouds, remained secret for a long time. The titanium atmosphere is based on nitrogen, as on Earth, but contains other gases, for example, methane. If the density of methane is large enough, the methane rain can go on titan. The existence of large bright spots on the satellite surface suggests that liquid seas can be located on the surface, which will certainly consist of methane. There may be a lot of time, but Titan is one of the most suitable places to find life.
