There are two major motions affecting the Earth: its rotation around its axis, and its rotation around the Sun (which we call 'revolution'). While the rotation of the Earth on its axis causes the nightly movement of the stars across the sky, the revolution is responsible for the fact that we can see different parts of the sky at different parts of the year.
