text: WASHINGTON, DC - DECEMBER 3: In this handout provided by NASA, an aircraft taking off from Ronald Reagan National Airport is seen passing in front of the moon as it rises on December 3, 2017 in Washington, DC. Today's full Moon is the first of three consecutive supermoons. The two will occur on Jan. 1 and Jan. 31, 2018. A supermoon occurs when the moon's orbit is closest (perigee) to Earth at the same time it is full. (Photo by NASA/Bill Ingalls via Getty Images
