An extra special--dare we say, super-sized---lunar extravaganza will occur Sunday night. A Full Cold Supermoon will be visible, weather-permitting. It will also be the only supermoon of 2017.
So what exactly is a Supermoon, and what makes it so glorious?
According to NASA, a supermoon occurs when the full moon reaches its shortest distance from Earth, called its “perigee,” in its 27-day elliptical orbit. The combination of the moon’s perigee and the full moon will make the moon look about 14 percent larger and 30 percent brighter than normal.
The full moon occurs at 10:47 a.m. EST on Sunday and will reach its perigee on Monday morning at 3:45 a.m. EST. At the time of perigee, the moon will be 222,135 miles away from Earth, which is about 16,000 miles closer than average. The moon will look largest when its closest to the horizon just after sunset and if you want to see extra lunar detail you can grab a telescope or binoculars.
If you miss out on this supermoon, have no fear! Although this is the only supermoon of 2017, this will be the first of three supermoons through January 31, 2018. The next supermoon will be January 2 and yet another will occur on January 31. The January 31 supermoon will be extra special because there will also be a total lunar eclipse and it will be the second full moon of the month, making it a Blue Moon.
So over the next couple of nights, if weather cooperates, take a moment to gander upward at the evening sky and marvel at the view of the bright Supermoon.
