The Solar System is a system of planets, in the center of which is situated a bright star, a source of energy, heat and light - the Sun. The Solar System includes 9 planets and more than 63 their satellites, several dozen of comets and large number of asteroids. In the center of Solar System is situated the Sun, around which in orbits revolve the planets. The Sun is a giant ball of fire of very high temperature, consisting of plasma (ionized gas), composed from hydrogen and helium. There are two large groups of planets: terrestrial planets - Mercury, Venus, Earth and Mars, they are small in size with a rocky surface and are situated nearer to the Sun; planets giants - Jupiter, Saturn, Uranus and Neptune, large planets composed mostly of gas and characterized by the presence of rings, consisting of ice, dust and many rocky pieces. The planet Pluto doesn't fall into any of these groups, because despite its presence in the Solar System, it is situated too far away from the Sun and has a very small diameter.
