Apogee/Perigee NASAOn March 19th, the moon will be closer--and thus bigger--than it's been in two decades On March 19th, the moon will be closer to Earth than it's been since 1992. The full moon that night will appear about 14 percent larger and significantly brighter than usual, but despite the brightness, the supermoon has a dark side. Supermoons have been linked to massive natural disasters in the past, from earthquakes to floods--but that connection is typically touted by astrologists. Astronomers and scientists, with typical drollness, say a catastrophe is unlikely. March 19th marks this year's lunar perigee, the point in the moon's orbit at which it is closest to Earth. It's the moon's elliptical orbit that's responsible for the differences in distance between the moon and Earth (the opposite, the point at which the moon is farthest from the Earth, is called the lunar apogee). This month's perigee will leave the...
