Tonight’s full moon will appear 14% bigger and 30% brighter than it has in bout 86 years, and all you have to do to enjoy a once-in-a-life-time event is look up.
Although supermoons occur once every 14 months on average. However, tonight’s supermoon is extra super because the moon will be even closer to Earth than usual. The moon will be 221, 524 miles from earth, compared with an average distance of 238, 900 miles.
The last time the moon sailed this close to Earth was on Jan. 26, 1948, when it came 30 miles closer. Next time won’t be until Nov. 24, 2034, when the distance between the two bodies will be 40 miles less.
The moon appears to shrink and grow in the sky becouse its orbit is not a perfect circle, but rather, a modest ellipse. As the moon swings between its closest point (perigee) and its furthest point (apogee), its distance to Earth varies by approximately 30, 000 miles. This translates to a size variation comparable to the difference between a nickel and a quarter.
So tonight take a minute of your time to gaze upon our wonderful moon, and remember that it is closer to us right now than it has been in more than half a century. What a special moment.
