If you look up at the moon in the next day or two, you might notice it looks bigger and brighter than usual. Bigger in fact, than it has appeared at any point in the last 68 years, NASA scientists say, CNN reports.
We won’t see another supermoon likes this until 2034, so make sure you get a look.
A “supermoon” occurs when the moon becomes full on the same day as its perigee, the point in the moon’s orbit when it is closest to Earth. The term is borrowed from the pseudoscience of astrology but has been adopted by popular culture and astronomers. Supermoons generally appear to be 14% bigger and 30% brighter than other full moons.
CNN adds that while such moons occur around every 13 months, November’s is a special one. According to NASA, this month’s supermoon “becomes full within about two hours of perigee – arguably making it an extra-super moon.”
