Almost all the planets of the solar system have moons.The exceptions are Venus and Mercury.Satellites of the planets are constantly open.Today there are about 170, including those belonging to dwarf planet, as well as those who "patiently" awaiting official confirmation.
Sun holds its facilities by gravity.Close to this yellow star turn small terrestrial planets, for that is the asteroid belt.Then there are the giant planets that do not have a solid surface, and consist mainly of hydrogen and helium.And completes the harmony of the second asteroid belt.
satellites of the planets of the solar system are varied in shape, size, some of them even have their own atmosphere.Most of them are formed from gas and dust.There are not just satellites of planets, asteroids and even - as a rule, they are very tiny.The largest in the solar system is considered Ganymede - "Moon" Jupiter.He's huge, he had to have its own magnetic field.The most puzzling is considered Io.On the satellite observed the constant volcanic activity with eruptions.However, Io's surface is always smooth - lava fills the crater and levels firmament like glaziruya it.Jupiter - the planet is unique.Along with his many companions, it forms a system similar to the sun.
not smaller set "moons" own and the other giant planets - Uranus and Neptune.Saturn there are more than 50 satellites.One of them - Titan - inferior to the value of a leader, and Ganymede has its own atmosphere consisting of nitrogen.They say that if they should look for life in the solar system - so only on it.In this satellite are often methane rain, while on the surface, perhaps are the most genuine sea, however, also methane.However, all the secrets of Titan keeps stubbornly opaque clouds.Remarkable and Triton - a satellite of Neptune.It also has the atmosphere.He was found craters, polar caps, and even the most real gas geysers.In our solar system Triton - only satellite, whose direction of rotation is opposite to the rotation of its planet.Miranda can not be called a beauty.The satellite of Uranus as if cut from different pieces, but is varied mountain scenery.
satellites of the terrestrial planets at least curious and original, although presented in a much smaller number.Earth - the only inhabited by living organisms body in the solar system, has as its companion moon.Its diameter is equal to a quarter of the earth.Moon - the largest moon in relation to the size of its planet.Others have no land other than artificial."Red Planet" Mars is accompanied by two natural satellites of small size and irregular shape - Phobos and Deimos.They turned to their planet is always on one side.By the way, there is a legend that life on Mars is still there, but hard evidence has yet been found or is not published.Satellites of the planets are not present in this group of two planets - Venus and Mercury.They are too close to the Sun, most likely, their "moon" burned.
How does this or that planet from a satellite, you can find out using a special service.However, in most cases it will be a simulated image.Until now the man was able to visit only one satellite - the Moon.
