Perigean Full Moon. Does tonight's full Moon look bigger than usual? It is! This full Moon occurs within 12 hours of perigee, when the Moon is at its least distance from the Earth--in this case a mere 57.1 Earth radii. If you could compare the Moon at perigee and apogee the difference would be obvious, but without any reference, most people never notice this. See our Inconstant Moon for details. If you're interested in taking your own photos of the Moon at apogee and perigee, shoot the perigee tonight or tomorrow, July 3rd. Reasonably good apogean full Moon opportunities occur on December 27th, 2004 and January 23rd 2005; use our Perigee and Apogee Calculator to explore further.
