As with all planets it is spherical in shape, although some ancient civilisations thought that the Earth was flat! It orbits around the Sun, and is the third planet out from the centre of our Solar System.
It is the only place outside of the Earth that humans have ever been! rocky, dusty sphere that goes round the Earth. We can often see the Moon on a clear night, but it does appear to change shape during the 28 days it takes to orbit the Earth.
The Sun provides the light and heat that we have during the daytime, it is the energy it provides which keeps all things on Earth alive. The Sun is massive, and over a million Earth's could fit inside it! It is the Earth's movement around the Sun once a year that leads to the four seasons of Spring, Summer, Autumn and Winter.
