Mercury is the planet closest to the Sun. This makes it very difficult to observe from Earth. It can only be seen in the evening or in the morning, and then only for a short time at dusk or dawn.
Mercury looks very similar to the Moon, but lacks the bright contrasts that characterise the Moon's front side. Mercury therefore resembles the back side of the Moon more closely. Like the Moon, Mercury is covered with craters, more than any other planet in the solar system. The poster explains exactly how these craters were formed. On Earth, most of the impact craters caused by meteorites have long since been eroded. Only a few very young craters have been preserved or are still visible in outline. However, these have enabled scientists to study the formation of such impacts in detail.
