SAN FRANCISCO (KCBS) — If you’re a fan of super moons, you’re in for the treat of the century – so far.
NASA says an “extra-super moon” will light up the night sky November 14th, and it will be the closest one to date in the 21st century.
A super moon occurs when a new or full moon is ”within 90-percent of its closest approach to Earth in a given orbit,” according to NASA.
A super moon coming up on December 14th will become full on the same day as perigee, the point in the moon’s orbit when it is nearest to the earth.
The November 14th super moon will become full within two hours of perigee, making it extra special.
“A supermoon, or perigee full moon can be as much as 14-percent bigger and 30-percent brighter than an apogee full moon,” according to the agency.
But, the December 14th super moon will wipe out the view of the Geminid meteor shower with its brightness.
