Post by: doit_the_clown on Mar 16, 2017 The Moon is seen to keep one face toward the Earth at all times. If viewed from a point directly above the plane of the planetary system, how does it have to rotate in order to maintain this alignment?
A) It must rotate once per day, to maintain its direction toward the Earth. B) It must not rotate at all because we always see the same face from Earth. C) It must rotate once per year as the Earth and the Moon orbit the Sun together. D) It must rotate once per month, or once per orbit around the Earth.
