Planets for Kids

Here on Planets for Kids we will explain facts about the planets within our Solar System. There are 8 planets that orbit or move around our Sun and they are called : Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. These 8 planets can then be separated into two planetary categories, Terrestrial Planets and Gas Giants.

The four Gas Giants can be spilt again into a sub category called Ice Giants which consists of Uranus and Neptune due to their makeup being made up of large quantities of ice and rock.

In the image below you might also spot a dwarf planet called Pluto beyond the orbit of Neptune. This was once classed as a planet when it was discovered in the 1930’s. However during he 1990’s Pluto’s classification was changed to a dwarf planet as due to the discovery of several objects of similar size in the Kuiper belt. The Kuiper belt is the outer Solar System, further out from planet Neptune.

The Planets In Order

The Terrestrial Planets consist of Mercury, Venus, Earth and Mars, and the Gas Giants which do not have solid surfaces are Jupiter, Saturn, Uranus and Neptune. The 4 Gas Giants can be spilt again into a sub category called Ice Giant which consists of Uranus and Neptune due to their makeup being made up of large quantities of ice and rock. In your journey through the Solar System you will learn fantastic facts and figures about all the planets, with help from our team of Robonauts.
