A "Super Moon" will rise in the east at sunset on Saturday evening. This unusually large full moon -- known as a super "perigee moon" -- will be the biggest in almost 20 years,
according to NASA.
"The last full moon so big and close to Earth occurred in March of 1983," says Geoff Chester of the U.S. Naval Observatory in Washington D.C. "I'd say it's worth a look."
