Our Solar System


Our solar system consists of the sun, nine planets which orbit around the sun and some smaller bodies like moons and comets.

The orbits of all except two planets, lie in the nearly the same plane (inclined by less than 3,4°); so that we can say: the solar system is disk-shaped. Pluto and Mercury are the odd ones out, with Pluto's orbit inclined at 17,2° and Mercury's orbit inclined by 3,4° to earth's orbit.

All planets revolve counterclockwise around the sun - as seen from the north.
