Almost all the planets in the solar system have satellites. Exceptions are Venus and Mercury. Satellites of the planets are constantly opening. Today, there are about 170 of them, including those belonging to dwarf planets, as well as those that are “patiently” awaiting their official confirmation.
The sun holds its objects by gravity. Next to this yellow star are the small planets of the earth group, behind which lies the asteroid belt. Next are the giant planets, which do not have a solid surface and consist mainly of hydrogen and helium. And the second belt of asteroids completes harmony.
The satellites of the planets of the solar system are diverse in shape, size, some of them even have their own atmosphere. Most of them were formed from gas and dust. Not only satellites of planets are known, but even asteroids - as a rule, they are very tiny. The largest in the solar system is Ganymede - the "moon" of Jupiter. It is so huge that it is forced to have its own magnetic field. Io is considered the most mysterious. On this satellite, constant volcanic activity with eruptions is observed. However, the surface of Io always remains smooth - lava fills the craters and levels the firmness, as if glazing it. Jupiter is a unique planet. Together with its many satellites, it forms a system similar to the sun.
No fewer “moons” are also owned by other giant planets - Uranus and Neptune. Saturn has more than 50 satellites. One of them - Titan - is second only to the leader Ganymede and has its own atmosphere, consisting of nitrogen. They say that if it is worth looking for life in the solar system - it is only on it. Methane rains often occur on this satellite, and on its surface, real seas may be located, although also from methane. However, Titan stubbornly keeps all its secrets behind opaque clouds. Noteworthy is Triton, the satellite of Neptune. It also has an atmosphere. Craters, polar caps and even real gas geysers were discovered on it. In the Solar System, Triton is the only satellite whose rotation direction is opposite to the rotation of its planet. Miranda cannot be called beauty. This
satellite of Uranus seems to be cobbled together from various pieces, but differs in a variety of mountain landscapes.
The satellites of the terrestrial planets are no less curious and original, although they are represented in much smaller numbers. Earth - the only body inhabited by living organisms in the solar system, has the moon as a satellite. Its diameter is a quarter of the earth. The moon is the largest satellite in relation to the size of its planet. Earth has no other than artificial ones. The "red planet" Mars is accompanied by two natural satellites of small size and irregular shape - Phobos and Deimos. They are turned to their planet always on one side. By the way, there is a legend that
life on Mars did exist, however, reliable evidence has not yet been found or published. The satellites of the planets are absent from two
planets of this group - Venus and Mercury. They are too close to the Sun, most likely, their "moon" burned out.
What this or that planet looks like from the satellite, you can find out using a special service. However, in most cases it will be only a simulated image. Indeed, so far man has managed to visit only one satellite - the moon.
