I think you're asking how the earth moves in space- as in orbit.
If you remember, the earth has a center of metal that creates a magnetic pull. That's why we can use compasses. It is what turns, or orbits, the Earth.
Similarly, the sun has a gravitational pull on the earth- as well as the moon. It is vital we have this pull, as it rotates us in a way that we don't feel it. The Moon helps to contradict our pull the Sun, so we don't spin any faster.
I hope this helps!
