Mystery Hour Question
Why do all the moons not rotate whereas the planets do? Kevin, Camberley
Name: Jeff, Ealing.
Qualification: Visited Johnston Space Centre in Houston and asked someone at NASA.
Answer: The moon does rotate.
It doesn’t appear to because it rotates on its Axis at roughly the same duration that it takes to go round the planets, so to people on the earth it looks as though it doesn’t move when it does.
