In our Solar System there are 8 planets, four indoor, rocky and small, and four outer, giant and gaseous. Of these eight planets, two have no satellites spinning around them, they are Mercury and Venus. All other planets, including Earth, have at least one. Our satellite is called the Moon, and by extension you can call moons to other satellites.
The two largest planets in the Solar System, Jupiter and Saturn, that of the famous rings, have the most moons: more than sixty each. Earth, with one, and Mars, with two, are the least.
Among the moons of the Solar System there are fascinating worlds, such as Europe, which may house primitives and strange life forms. The volcanic hyperactivity of Io, the mountains over twenty thousand meters high of Iapetus and the frozen geysers of Triton, are true wonders of nature. And many, many mysteries, such as the orbits of Hyperion and Nereida or the binary system formed by Charon and Pluto.Solar System Satellites
