The Moon and the Sun both rotate counterclockwise. There is evidence that the Sun is moving. The center of the Milky Way is found by looking in the direction of the constellation Sagittarius. Sagittarius is a summer constellation in the northern hemisphere. The Milky Way then moves around the center of the galaxy.
Scientists deduce thi s information by observing thousands of nearby stars.
The Sun does rotate around its axis, although it rotates faster at the equator than at the poles. At the equator, the rotation period is 25 Earth days, while at the poles it is 35 Earth days. The Milky Way also rotates, although different parts rotate at different rates. This keeps the arms from all running into each other. All Rights Reserved.
