Solar System

Our solar system consists not only of the Sun and the eight planets that revolve around it, but of many other objects existing in Sun’s gravitational field, like asteroids, comets, Kuiper’s belt objects and Oort’s Cloud objects.

Solar system is divided in four areas.  The Inner Planets (Mercury, Venus, Earth and Mars), the four planets which are made of stone and have almost the same constitution with Earth.  The Asteroid belt, an area with small objects between Mars and Jupiter.  The Outer Planets or Gas planets (Jupiter, Saturn, Uranus and Neptune).  They consist mostly of gases and they are much bigger than Earth.  And the area in the Outer solar system where Pluto, Kuiper Belt and Oort Cloud belong.
