The moon — our planet's only natural satellite — sits an average of 238,855 miles (384,400 km) away from Earth. Yet while many a bold cosmonaut has ventured into space, only a select dozen have had the privilege of stamping their bootprints on its dusty surface.
But how many of these 12 — all American men who were part of the Apollo missions — can you name? In this moon walking quiz, you'll have six minutes to get as many as you can.
And remember, in the words of U.S. President John F. Kennedy, you're answering these quiz questions "not because they are easy, but because they are hard."
