Monday’s Supermoon Is Going To Be More Super Than Usual

A notable supermoon is coming. NASA considers a moon a “supermoon” when it appears up to 14 percent bigger and 30 percent brighter when it’s at its farthest point in orbit, but not all supermoons are created equal. The one appearing Monday (November 14th) night will make its closest pass to Earth since 1948. The moon’s perigee, or nearest orbital approach to Earth, occurs at around 6 a.m. eastern time Monday morning, but the moon will also be big and brilliant the night before, assuming skies are clear. While supermoons themselves aren’t particularly rare (we got them in October, November, and December of 2016)– this one is exceptional, as it’s the closest pass in nearly 70 years. The next time it gets this close again will be November 2034. (PopSci
