Look for

The dark “seas” are old lava plains, the “man in the Moon” in the north and a rabbit in East Asia. Binoculars along the line between day and night show craters in sharp relief.

Did you know

It is drifting away from us by about 3.8 cm a year — measured by bouncing lasers off mirrors the Apollo astronauts left behind.

History

Twelve people walked on it between 1969 and 1972.
