Last weekend, sky-watchers all around the world enjoyed a supermoon of 2017, which looked especially close, large and bright. The moon became totally full at 10:47 a.m. EST on Dec. 3rd, and the supermoon was 7% larger and 15% brighter than normal. If you did’t catch up the “supermoon-watching fad” this year, without a long wait, the “supermoons” of 2018 will occur twice on January 2nd and January 31st, 2018.
What is a supermoon?
The moon makes an elliptical orbit around the earth once every 27 days, with a full moon happening once every 29.5 days. When the moon is full and its orbit brings it closest to Earth, a supermoon(scientific name: perigee syzygy) occurs.
