A.The satellite never moves relative to the moon
B.The satellite travels continuously away from the moon.
C. The satellite remains at a constant distance from the moon.
D.The satellite continuously move closer and farther away from the mood.

Answer 1

If each day the satelite orbits the earth its going faster than the moon and is passing it, so the satellite continuously moves closer and further away from the moon. like if you were standing watching a race then the racers would be moving away then towards you then away again

Answer 2

Answer: D.The satellite continuously move closer and farther away from the moon.

The moon rotates on its axis and revolves around Earth in 27 days. The satellite is orbiting Earth once per day.

In moon 's frame of reference, the satellite would be in motion. Sometime it would be away and sometimes closer. From moon, we would observe satellite to rotate about the Earth. The satellite would get eclipsed by the Earth sometimes when it would go behind it as viewed from moon.
