The only supermoon of the year could be seen in the sky Sunday night in some parts of the world, while other areas were too overcast to catch a glimpse of the beautiful sight.
The term “supermoon” has only been used for about 40 years, and according to Space.com:
A supermoon needs two key ingredients to occur. The moon needs to be at its closest approach, or perigee, to the Earth in its 27-day orbit. The moon also needs to be at the full phase, which happens every 29.5 days when the sun fully illuminates the moon. Supermoons only happen a few times a year (at most) because the moon’s orbit changes orientation while the Earth orbits the sun — that’s why you don’t see a supermoon every month.
NASA states on their website that “The name ‘supermoon’ was coined by an astrologer in 1979 and is often used by the media today to describe what astronomers would call a perigean (pear-ih-jee-un) full moon: a full moon occurring near or at the time when the Moon is at its closest point in its orbit around Earth. The term gives preference to the geometric alignment of Sun-Earth-Moon and allows the occurrence of perigee into a wider time period than the actual instant of perigee (up to about two weeks, which is almost half of the Moon’s orbit).”
Many took to social media to rave about the beautiful glowing moon. Dennis Wyrick posted the following photo to Instagram showing the view from Tampa Bay, Florida:
