Question 15. Why do we see only one side of the moon from the earth? (a) Because of moon moving around the earth in 27 days (b) 27 days also taken in one spin (c) Both (a) and (b) (d) None of these Answer
The Moon orbits Earth once every 27.3 days and spins on its axis once every 27.3 days. This means that although the Moon is rotating, it always keeps one face toward us. Known as “synchronous rotation,” this is why we only ever see the Moon's nearside from Earth.
