A trip across the Solar System: Mercury

Mercury, a heavily cratered planetMercury, a heavily cratered planetMercury is the nearest planet to the Sun. It is the smallest planet in the Solar System. Named by the Romans after the winged-foot messenger of the gods, Mercury orbits the Sun more quickly than any other planet, taking just 88 days. Mercury can be seen from Earth, but not very easily: it is always low in the dawn or twilight sky close to the Sun.
