View original image[Asia Economy Reporter Kim Bong-su] This Wednesday (the 13th), a larger and brighter 'Supermoon' will rise than usual.
According to the Gwacheon National Science Museum on the 10th, the moon rising over Korea on the 13th will be a 'Supermoon' that is 14% larger and up to 30% brighter than when it is smallest. This is because the moon will be observed at its closest point to Earth (approximately 357,400 km).
This Supermoon is the first in about a year since May 26 last year, rising at 7:52 PM and setting at 4:05 AM the next day. At this time, the distance to the moon is 357,417 km, and the moon's apparent diameter is 33.42 arcminutes.
A Supermoon refers to a full moon (mang) or new moon (sak) occurring near the perigee, generally meaning a full moon observed near the perigee. The Supermoon is 14% larger and up to 30% brighter than the smallest moon.
The term 'Supermoon' was first proposed in 1979 by American astrologer Richard Nolle, but the official astronomical term is perigee syzygy.
