Tonight, if you look up into the night sky and it seems that the Moon is significantly bigger don’t worry. The Moon is not on a trajectory to crash into Earth, it simply will be closer to the Earth due to its elliptical orbit. That orbit results in the Moon being closer on one side of the planet than the other. When it’s at this point, scientists and those in the know call it a “perigee moon.”AdChoices广告Saturday’s perigee moon will be about 50,000 kilometers, or 31,069 miles, closer to Earth than when at its apogee, though the Moon will still be 356,577km or 221,567 miles away. Geoff Chester, of the U.S. Naval Observatory in Washington D.C., says that on March 19th the Moon will be one hour away from perigee which only happens every 18 years or so. The result is what looks like a gigantic full Moon in the sky that is expected to be 14% larger and 30% brighter than a typical full moon.The Moon will look even bigger when beaming through a foreground object like a tree as a result of something called “the Moon illusion.”Even more than a normal full Moon, this “super Moon” gets a bad reputation for triggering natural disasters thanks to stories posted on the Internet. NASA says the facts don’t back that accusation. They point to the “super Moon” of March 1983 and the “almost super Moon” of December 2008 that resulted in no natural disasters occurring. In fact, the National Oceanic and Atmospheric Administration (NOAA) states that lunar gravity at perigee will only pull tide water nor more than an inch or so higher though local geography could result in a pull of up to six inches. That may be alarming if you’re an insect living on the beach, but it shouldn’t be to humans.Read more at NASA.
