The moon moves around the earth in about ________.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 27 days
- The Moon takes about one month to orbit Earth (27.3 days to complete a revolution, but 29.5 days to change from New Moon to New Moon). As the Moon completes its 27.3-day orbit around Earth, both Earth and the Moon are moving around the Sun.
-
The moon moves in a uniform circular motion around the earth. It is the force of gravity on the earth that keeps the moon in a circular orbit around it.
