Planetary science: How Mercury got its spin
Stanley F. Dermott1
Abstract
The orbital period of Mercury and its period of rotation are known to be in a 3/2 ratio, but the chances of the planet reaching this state seemed so small as to be unfeasible — until now.
Like most of the large satellites in the Solar System, the Moon's orbital period and its period of rotation are the same: the Moon completes both an orbit of the Earth and a rotation about its own axis in 27.3 days, and hence always keeps the same face towards the Earth.
