Watch out for the full moon on Monday night, November 14, that will appear exceptionally brighter and closer than it has in 68 years.
The moon will be closest to Earth at around 7:21 p.m. in the Philippines, said Dario dela Cruz, chief of the space sciences and astronomy section of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
The average distance between the Earth and the moon is 384,400 km, but it will be at 356,621.66 km on Monday.
“This means we’ll be seeing a closer and larger apparent diameter moon this year—a supermoon,” dela Cruz added. He also recommended watching the supermoon at the eastern horizon, barring overcast skies and light pollution.
While the so-called supermoon happens every year—causing higher-than-usual tides—dela Cruz said the full moon has not been as close to Earth since January 26, 1948.
Supermoon, dela Cruz pointed out, is actually a modern astrological term coined by Richard Nolle to define “a new or full moon that occurs when the moon is within 90 percent of its closest approach to Earth in a given orbit.”
This astronomical event is called perigee full moon, a full moon that is as much as 14 percent bigger and 30 percent brighter than an apogee full moon, a full moon farther to Earth than average, the U.S. National Aeronautics and Space Administration (NASA) said.
When the moon is closer to Earth, it induces more gravitational pull that results in greater variation in high and low tides.
Dela Cruz said the moon won’t be seen this close to Earth again until November 26, 2034.
