The four planets that are closest to the sun are called Inner Planets.

The Inner Planets are Mercury, Venus, Earth and Mars. These planets are quite solid and are made up of rock and metals. They are considered to be heavy and therefore move slowly. They are also small planets with a diameter of no more than 13 000 km.

Jupiter, Saturn, Uranus and Neptune make up the Outer Planets. The outer planets tend to be made of gases and are therefore not really solid. The two main gases are helium and hydrogen. Sometimes people think of these giant gas planets as huge balloons floating in space. The outer planets have a diameter of over 48 000 km.

The Inner Planets are separated from the Outer Planets by the Asteroid Belt.

So if you actually think about it if we lived on Mecury or Venus it would be too hot but if we lived on one of the outer planets itt would be too cold.
