How long is the moon’s rotational period? A. twice its period of revolution B. one-fourth its period of revolution C. half its period of revolution D. the same as its period of revolution

Sagot :

How long is the moon’s rotational period - D. the same as its period of revolution. The moon takes 27.3 days to rotate once on its axis. The moon takes 27.3 days to revolve the Earth once.

Answer: D. the same as its period of revolution

Explanation: The moon orbits around the earth, i.e. its revolution lasts 27,322 days. Also, the moon rotating around its own axis takes approximately 27 days. The result is that it seems that the Moon does not move, and that one side of the moon is always in the dark, "dark side of the moon." When it comes to a time period of 27,322 days required for the moon to rotate around its axis, and to orbits the Earth, it is the so-called sidereal month. There is also a synodic month that lasts for an average of 29.53 days, and this is a period necessary for the Moon to reach the same visual phase.
