Perigee Moon January 10, 2009

What is a Perigee Moon?
“Johannes Kepler explained the phenomenon 400 years ago. The Moon’s orbit around Earth is not a circle; it is an ellipse, with one side 50,000 km closer to Earth than the other. Astronomers call the point of closest approach “perigee,” and that is where the Moon will be this weekend.

Perigee full Moons come along once or twice a year. 2008 ended with one and now 2009 is beginning with another. It’s the best kind of déjà vu for people who love the magic of a moonlit landscape.”
