On this special astronomical night, the full moon will be at lunar perigee, the nearest approach in its orbit around Earth, but in this case, it will be at its closest proximity to us in 18 years, reports Life's Little Mysteries, Space.com's sister site.
With our neighboring satellite scheduled to light up the sky from only 221,567 miles away, some are wondering if its close proximity will cause any unexpected problems for us.
We all know, most likely from elementary school science or episodes of "Nova," that the moon's gravitational pull on our home planet affects the ocean tides. But with the upcoming extreme closeness of the moon, will any tide increases trigger other possible problems, like earthquakes?
"A lot of studies have been done on this kind of thing by USGS scientists and others," said John Bellini, a U.S Geological Survey geophysicist. "They haven't found anything significant at all."
And according to John Vidale a seismologist at the University of Washington in Seattle, we'll never notice anything different about tonight's lunar perigee. "It's somewhere between 'it has no effect' and 'it's so small you don't see any effect.'"
In case you prefer to plan your life according to the movements and positions of the moon, sun and planets, renowned astrologer Richard Nolle lays claim to the term "supermoon" on his Astropro website.
Nolle agrees with the majority of scientists that this evening's supermoon event isn't likely to be, literally, Earth-shattering.
"It won't be the case that all hell will break loose all over the world," he wrote.
"The worst that can happen, if the worst doesn't happen, is that you end up with a stock of fresh batteries and candles, some extra bottled water and canned goods, maybe a full tank of gas and an evacuation bag packed just in case."
At the very least, when the moon rises at sunset in the eastern sky, it'll probably produce a great photo op.
