Our Solar System

To study the Solar System, there are astronomers that are experts or students that study Astronomy. Astronomy is the branch of science that deals with celestial objects, space, and the physical universe as a whole.

Introduction

There are nine planets in our solar system. These planets circle around or orbit the Sun. The closest planet to the Sun is Mercury and the furthest planet from the Sun is Pluto. However many today do not count Pluto as a planet, so this would leave Neptune as the futhest planet.

The Solar System Song

The Solar System is made up of planets, moons, comets, asteroids, dust, gas and lots more.

We have the Inner Solar System which has Mercury, Venus, Earth and Mars. These are closest to the sun and are called the terrestrial planets simply because the have very solid rocky surfaces.

The Outer Solar System has Jupiter, Saturn, Uranus, Neptune these are sometimes called the gas giants

Inner Solar System vs. Outer Solar System

The sun has such a powerful gravity that it tries to pull the planets towards it while the planets try to fly away. In the end the planets are left in the middle floating around the sun.
