Mercury is the first planet out from the Sun and the smallest of the eight. On this sheet it fills the page, so its craters are easy to colour one at a time.
Children who like repeating shapes tend to enjoy this one: each crater can be a slightly different shade of grey, brown or blue.
Mercury orbits nearer the Sun than any other planet, and it races around it in just 88 Earth days. That is why a year on Mercury is shorter than one school term.
Mercury has almost no atmosphere to hold heat in, so the side facing the Sun becomes scorching while the shaded side turns bitterly cold. The difference between them is greater than on any other planet.
With no thick air to burn up incoming rocks, everything that hits Mercury leaves a mark, and nothing washes those marks away. The craters on this sheet have been there for billions of years.
