Moonlit Washington Monument. Today’s Image of the Day from NASA shows a supermoon rising behind the Washington Monument on June 23, 2013.
That year, the moon reached its perigee, which is the closest point of its orbit to our planet.
On June 23, the moon was over 30,000 miles closer compared to its furthest distance from the Earth and appeared 30 percent brighter than a typical full moon. Also you can see the cloudy haze overlapping the moon. The Moon is thought to have formed about 4.51 billion years ago, not long after Earth. The most widely accepted explanation is that the Moon formed from the debris left over after a giant impact between Earth and a Mars-sized body called Theia.
