The full moon rises behind the cross of a church in Hyderabad on March 19, 2011. Full Moons vary in size because of the oval shape of the Moon's orbit. It is an ellipse with one side (perigee) about 50,000 km closer to Earth than the other (apogee). Nearby perigee moons are about 14 percent bigger and 30 percent brighter than lesser moons that occur on the apogee side of the Moon's orbit. According to The US Naval Observatory in Washington, D.C. "The full Moon of March 19 occurs less than one hour away from perigee -- a near-perfect coincidence that happens only 18 years or so."
