So you think you know the Moon
So after all the clicking on Moon Zoo you should know what the lunar surface looks like! But do you? Are you a true lunarphile? Like the Moon, Mercury is also rocky and heavily cratered. Can you spot the difference?
Study the two pictures below and decide which shows lunar craters and which shows craters on Mercury. You can vote on the Moon Zoo forum.
Voting ends Sunday 16 October. Answer next week!
