Beofre this year one planet: Earth would be said to be the only actively tectonic planet in our system. However now data from a NASA spacecraft, Messenger, shows that Mercury is shrinking. It is showed by a series of small cliffs jutting out of the surface. Scans of Mercury have revealed previously unseen ripples in the surface showing us it is tectonic itself. Not in the same way as th earth but the data taken by messenger has only began to help us learn more about the planets around us.
