A supermoon is the coincidence of a full moon or a new moon with the closest approach the Moon makes to the Earth on its elliptical orbit, resulting in the largest apparent size of the lunar disk as seen from earth. The technical name is the perigee-syzygy of the Earth-Moon-Sun system. The term originated from astrological circles.
There are three supermoons for 2016, one was on October 24th, the brightest supermoon will be on November 14th, and one more before the end of the year on December 14th. Since the moon is closer to the earth, the moon will appear larger in the sky and reflect more light toward the planet. Analysts expect the moon to appear 14 percent larger and 30 percent brighter than normal. The moon will be closest it has been to the earth in 68 years.
“I’ve been telling people to go out at night on either Sunday or Monday night to see the supermoon,” said Noah Petro, project analyst for NASA’s Lunar Reconnaissance Orbiter mission, in a NASA release. “The difference in distance from one night to the next will be very subtle, so if it’s cloudy on Sunday, go out on Monday. Any time after sunset should be fine. Since the moon is full, it’ll rise at nearly the same time as sunset, so I’d suggest that you head outside after sunset, or once its dark and the moon is a bit higher in the sky.”
