Ten of the most unusual moons of the Solar System

Earth's solar system consists of the sun and nine planets. Planet of the solar system does not suffer from lack of attention, so no attention there are other equally important objects system- such as satellites. But they are interesting to their planets.

10. Ganymede - a great companion

Ten of the most unusual moons of the Solar System

Ganymede may be confused with the moon, but there is a small difference - in size. Ganymede - the largest moon of Jupiter and the entire solar system in general. It is so huge that it has its own magnetic field.

9. Miranda - ugly companion

Ten of the most unusual moons of the Solar System

Miranda considered the ugly duckling of the solar system. At first glance, it seems as if someone just blindly from pieces of the satellite and sent it to revolve around Uranus. Miranda is one of the most diverse landscapes in the Solar System, with its steep mountain ranges, valleys - crowns and canyons, some of which are up to 12 times deeper than the Grand Canyon. If one such throw a stone, it will reach the bottom in just 10 minutes.

8. Callisto - a satellite with the largest number of craters

Ten of the most unusual moons of the Solar System

Callisto, Jupiter's moon, a pimply teenager solar system. Unlike other celestial bodies of the same size, Callisto has no geological activity that could protect its surface. Therefore, the satellite and is the most "beaten". Craters on it so much that they become superimposed on one another to form a ring inside the other integers craters.

7. Dactyl - satellite asteroid

Ten of the most unusual moons of the Solar System

Dactyl - the smallest moon of the solar system, its width is only miles. Pictured asteroid Ida and Dactyl - it's just a tiny dot on the right. Dactyl more amazing facility, because it does not revolve around the planet, and around the asteroid. Previously, astronomers thought that the asteroids are too small to have moons. And here and there.

6. Epimetheus and Janus - satellites, narrowly escaped a collision

Ten of the most unusual moons of the Solar System

Epimetheus and Janus - Saturn's moons, in which almost one orbit, perhaps because in the past they were one satellite. But here's the thing: every 4 years they change places with the near-collision.

5. Enceladus - the carrier ring

Ten of the most unusual moons of the Solar System

Enceladus is one of the major domestic satellites of Saturn. He is also one of the objects, which reflect almost 100% of the light. The surface is covered Enceladus geysers, ejection space ice particles and dust, which are the source of the E ring of Saturn.

4. Triton - from ice volcanoes

Ten of the most unusual moons of the Solar System

Triton - the largest moon of Neptune. It is also the only satellite of the solar system rotating around its planet in the opposite direction from the direction of rotation of the planet itself. Triton is volcanically active. But if other volcanoes emit lava, volcanoes erupt on Triton water and ammonia, which are frozen on the surface.

3. Europe - with large oceans

Ten of the most unusual moons of the Solar System

Europe, another satellite of Jupiter, has one of the smoothest surfaces in the solar system. It's because the entire moon is one continuous water ocean under the ice layer. But this water exists only due to tidal heating of Jupiter. In this ocean of water 2-3 times greater than on Earth.

2. Io - volcanic hell

Ten of the most unusual moons of the Solar System

Because of the tremendous force of friction Jupiter, Io's volcanic activity occurs continuously. This satellite recalls Mordor from "Lord of the Rings." In fact, the entire surface of Io is covered with volcanoes, and eruptions occur so often that the "Voyager" was able to remove the process (red spots in the picture). Io no craters as lava fills and smoothes the surface of most of the satellite.

2. Titan - a home away from home

Ten of the most unusual moons of the Solar System

Titan - the strangest satellites in the Solar System. He only has a dense atmosphere (denser than on Earth), and what lies beneath opaque clouds remained a mystery for a long time. Titanium atmosphere is based on nitrogen, as in the world, but contains other gases such as methane. If the density of methane is large enough, can go on Titan methane rain. The existence of a large bright spots on the moon's surface suggests that the sea may be liquid on the surface that are sure to consist of methane. It may take a lot of time, but Titan - one of the most suitable places to look for life.
