Supermoon is a great opportunity for people to see the moon, not just for a moment, but it can be all night! "Said Noah Petro, a scientist from NASA's Goddard Space Flight Center.
Supermoon occurs when the moon is in the position of its closest orbit to the earth. Because of the elliptical lunar orbit, one side (apogee) is about 30,000 miles (50,000 km) farther from Earth than the other side (perigee).
Perigee nearest full moon looks about 14% larger and 30% brighter than what happened near the apogee orbit of the moon. Therefore, people are waiting for this moment, where the moon looks so close to the earth, big and bright, that it feels touched.
NASA predicts that the best supermoon will occur on January 31, 2018. This phenomenon will show a total lunar eclipse and can be witnessed from western North America across the Pacific toward East Asia.
"The lunar eclipse on January 31 will be visible during the moonset.The people in the eastern United States, where the eclipse will be partial, must get up early to see it," Petro said. "But this is a great opportunity to see the moon."
