The Universe - Mercury

Mercury is the planet closest to the Sun.  Even so, it is 58 million kilometres away from the Sun.

Mercury orbits round the Sun, but its orbit of the Sun lasts for only 88 days.

Mercury is a small planet.  

Its diameter is only 3100 miles, or 4990 kilometres.  

In many ways it resembles the Moon, with dark and light areas, and many craters caused by impacts.
