The Statue of Freedom atop the U.S. Capitol Dome is seen in silouette infront of the moon, or supermoon, on Monday, Nov. 14, 2016 in Washington. A supermoon occurs when the moon’s orbit is closest (perigee) to Earth. Early Monday morning, the moon was the closest it has been to Earth since 1948 and it appeared 30 percent brighter and 14 percent bigger than the average monthly full moon.
