Supermoon: Fact Vs. Fiction
“Fact: The closest perigee full Moon always comes just two weeks, either before or after, the farthest apogee new Moon! This year, it occurred on Halloween: October 31st, 2016, when the Moon reached a distance of 406,662 km, just 58 km short of its maximum distance.
Fiction: The tides will be significantly larger than normal. Although it’s true that the tidal forces will be slightly greater, they’re only 2% larger than last month’s full Moon. That means that if last month, there was a three foot (~1 meter) difference between high tide and low tide, there will be an extra ¾ths-of-an-inch (2 cm) difference; not even discernible without a measuring device.”
This coming Monday, November 14th, 2016, a full Moon will occur extremely close – within 90 minutes – of a very, very close lunar perigee. The Moon will come within 356,509 km of Earth while 99.9% full, making this the most “super” Supermoon Earth has seen in 68 years. No matter where you are on Earth, if you have clear skies, it’s worth a look, particularly right before dawn, where it’s at its closest and brightest. But what are the facts about a Supermoon, and what are the fictions? How does it impact the tides? How much closer does this Supermoon come than other close, bright full moons? Will there be an eclipse with it? Why is it called the Beaver Moon? And does it have anything to do with a woman’s menstrual cycle?
