Tonight's Wolf Moon

Why Is the Moon Looking Unusually Large?
Updated: Saturday, January 30, 2010 7:54 AM

The full moon through this Saturday will be the largest and brightest of the year. This is also called the Wolf Moon, which will be 14 percent wider and 30 percent brighter than a typical full moon.

The moon's orbit around Earth is not a circle, but an ellipse, with one side 50,000 km closer to Earth than the other. The point of closest approach is called the "perigee," and that is where the moon will be Friday night through Saturday morning.
