How much time does it take for the moon to revolve?
About 27.3 days.
365.24 days, exactly the same length of time as the earth takes. If the moon took more or less time than the earth does to revolve around the sun, even by a very small amount, then over a period of many years, the moon would either pull way ahead of the earth, or else fall far behind. That doesn't happen, because earth and moon revolve around the sun together, in the same time.
