There are eight planets in the Solar System. The four inner planets are Mercury, Venus, Earth and Mars while the four outer planets are Jupiter, Saturn, Uranus, and Neptune.
The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, and dust and gas.
Everything in the Solar System orbits or revolves around the Sun. The sun contains around 98% of all the material in the Solar System. Because the Sun is so large, its powerful gravity attracts all the other objects in the Solar System towards it.
When trying to remember the order of the planets in the Solar System there is a popular acronym that people use. "My Very Eager Mother Just Served Us Nine Pickles." If you can remember that then it will be an easier way to be able to name all of the planets.

The circumference measured around the equator is 24,901 miles. There are currently almost 7 billion people living on the Earth.
