Solar System


The Earth ROTATES (spins) around an imaginary line called an AXIS. It takes 24 hours or one day to rotate.

The Earth and other planets REVOLVE (move around) the Sun. The path is called an ORBIT. It takes one year (365 and a quarter days) for the Earth to revolve the Sun.

The Moon REVOLVES in an ORBIT around the Earth in about 1 month.
