LAPD chopper flies in a foregraund of the Super Moon in Los Angeles, California on May 05, 2012. Tonight's moon is set to appear 14 percent larger and 30 percent brighter from our perspective on Earth. The Supermoon lines up much closely with perigee – the moon's closest point to Earth. The 2012 May full moon falls some six minutes after perigee, the moon's closest point to Earth for this month. At perigee, the moon lies only 221,802 miles (356,955 kilometers ) away. Later this month, on May 19, the moon will swing out to apogee – its farthest point for the month – at 252,555 miles (406,448 kilometers) distant. (Photo by AFP/File, Joe Klamar)
