Wednesday’s Supermoon Is The Last Of 2019
The supermoon on Wednesday will be the third in three months, but it will also be the last of the year.
WGRZ reports, "The full moon is a supermoon because the moon will be at nearly its closest to the Earth. The term was first coined in 1979 by an astrologer named Richard Noelle. He defined a supermoon as a "new or full moon which occurs with the moon coming within 90 percent of its closest approach to Earth." That point where the moon is at its closest is called a perigree."
