  1. Mercury is a terrestrial planet, which means that is has a solid surface, like Earth. Mercury is very rocky, and its surface is pocked by thousands of craters. This is partly a result of having been hit by numerous objects during the early stages of the solar system. The spacecraft Messenger has been launched by NASA and it is scheduled to enter Mercury's orbit in March 2011. Messenger will spend a year near Mercury, photographing the planet and gathering information.
