This paper presents one analytical tidal theory for a viscoelastic multi-layered body with an arbitrary number of homogeneous layers. Starting with the static equilibrium figure, modified to include ...

The Moon exhibits synchronous rotation, a consequence of Earth's gravitational influence locking its rotational period to its orbital period. Despite synchronous rotation, observers on Earth can ...

Mercury might once have orbited the sun in a “synchronous” rotation, before being hit by a large asteroid that flicked the rocky planet into a strange orbit. A synchronous orbit is one in which a body ...
