In Roman mythology Mercury is the god of commerce, travel and thievery. Mercury is also known as Hermes, the messenger of the Gods, in Greek mythology. The planet probably received this name because it moves so quickly across the sky.

It was once believed that there was no water on Mercury, but this turned out to be false. Recent radar information shows evidence of ice at Mercury's north pole! The ice hasn't melted because it is protected from the Sun's heat by shadows of some craters.
Mercury has been visited by the Mariner 10 spacecraft. Mariner 10 has mapped a little less than half (45%) of Mercury's surface.
Scientists think that there may be *volcanic activity* on Mercury. They are still studying information sent to Earth from the Mariner spacecraft to make sure.
