A planet is a large, round ball of rock and/or gas that is in orbit around a star. There are 9 planets (that we know of) in our solar system. Some astronomers believe that there is a 10th planet, but this is not known for sure.  The planets in our solar system (in order from nearest to farthest from the Sun) are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto.
