How often does a large meteroid hit the Moon? Can I see such an impact?

FROM THE April 2011 ISSUE

How often does a large meteroid hit the Moon? Can I see such an impact?

Thomas Baker, Castle Rock, Colorado

Our Moon.

Nikos Haralampidis

Youт??ll need a small telescope to view average impact flashes because their brightnesses are around magnitude 7 to 10.

We think 2-pound rocks likely hit the Moon more than 260 times per year.
