Planets and their Moons

There are nine planets and close to sixty known moons in our Solar system. We have one moon with our planet, Mercury and Venus have none, and nearly all the others circle the giant outer planets with 23 moons circling Saturn and 16 around Jupiter. One of the moons called Titan which circles Saturn is 5120 kilometres across in size and is in fact bigger than both Pluto and Mercury. Most of the moons which circle the outer planets are made of gas and ice mixed with rock. Some even have volcanoes on their surface. Both planets and their moons do not have any light of their own, they can be seen only because they reflect the light of the Sun or the nearest bright star. The difference between the two is that a planet revolves around the Sun and a moon revolves around a planet and Moons are generally smaller than the planets they circle.
