RICHMOND, Va. (WTVR) – The “biggest” Full Moon of this year will occur this Saturday, May 5, 2012 at 11:34 p.m. EDT. On Saturday, the Moon will be closest to the Earth in its orbit, which is called the “perigee,” and thus appear ever-so-slightly larger to viewers on Earth. At a distance of 221,802 miles from Earth, this marks the closest approach to us as the Moon orbits around the Earth in an elliptical path, not an exact circle.
