Question: As we watch the Moon move acrossthe sky, how much is it moving, versus the Earth’s own movement?

Answer: When you watch the Moon movefrom east to west, it travels its own diameter in about 3 minutes. The speed atwhich we see it move is mostly due to the Earth’s movement, not the Moon’s. TheEarth’s movement accounts for 95 percent of the shifting position of the Moon. Theother 5 percent is actually the Moon itself moving.
