Biggest Supermoon in 70 Years Coming Your Way on November 14
If you only see one astronomical event this year, make it the November supermoon, when the Moon will be the closest to Earth it's been since January 1948. During the event, which will happen on the eve of November 14, the Moon will appear up to 14 percent bigger and 30 percent brighter than an average full moon. This is the closest the Moon will get to Earth until 25 November 2034, so you really don't want to miss this one.
Supermoons aren't all that uncommon - we just had one on October 16, and after the November 14 super-supermoon, we'll have another one on December 14. But because the November 14 Moon becomes full within about 2 hours of perigee, it's going to look the biggest it has in nearly seven decades."The full moon of November 14 is not only the closest full moon of 2016, but also the closest full moon to date in the 21st century," says NASA. "The full moon won't come this close to Earth again until 25 November 2034."Depending on where you're viewing it from, the difference between a supermoon and a regular full moon can be stark, or difficult to tell. If the Moon is hanging high overhead, and you have no buildings or landmarks to compare it to, it can be tricky to tell that it's larger than usual.But if you're viewing from a spot where the Moon is sitting closer to the horizon, it can create what's known as 'moon illusion'. "When the moon is near the horizon, it can look unnaturally large when viewed through trees, buildings, or other foreground objects," says NASA. "The effect is an optical illusion, but that fact doesn't take away from the experience."
