How many astronauts have been on the moon?
I'm not sure, but I think it may be around 9 or so. I know that the most exclusive club in the world is considered to be those who have walked on the moon, except for people who have slept with Jessica Simpson. For now.
There are about 12 astronauts, but now some people even land robots on the moon.
12, from 1969 to 1972.
