Celestial fans, you’ll want to turn your eyes to the skies. 2017’s only supermoon is happening this weekend, and here’s when it will look best in your time zone.
For those unfamiliar, a supermoon is when the slight variations in the Moon’s orbit lead it to be closest to Earth during a full moon. When this happens, it can look up to 14 percent larger and 30 percent brighter than usual.
According to Space.com, the Moon becomes totally full at 10:47 am EST on Sunday, December 3. It will reach perigee (the point where it is closest to Earth) that night at 3:45 am EST on December 4, so East Coasters will have to stay up pretty late if they want the best view, with those in Central (2:45 am), Mountain (1:45 am), and Pacific (12:45 am) time zones getting to hit the sack a little earlier.
But there’s good news for those who aren’t night owls: To the naked eye, a few hours won’t be make too much of a difference. Plus, the moon illusion—the way our brains register how giant the Moon looks when on the horizon—might make it look more impressive during its rise, anyway.
And apparently, we’ve already missed all the good supermoons; the Earth and Moon are moving farther apart each year. When the Moon was formed, it was just 14,000 miles away, and now it’s around 238,900 miles, with 1.5 inches added to the gap every year.
