This Saturday night, January 10, 2009, the biggest full moon of 2009 is coming. This is according to NASA.

Why is it bigger than the usual full moon that you see? It is because 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 Saturday. This happens only once or twice in a year. The last time it happened was December of 2008.

Low-hanging Moons look unnaturally large when they beam through trees, buildings and other foreground objects for reasons not fully understood by astronomers. A magic moment that happens when the perigee moon is near the horizon. Illusion mixes with reality to produce a stunning view.
