A supermoon is ready to take center stage in the night sky this Wednesday, but with an added twist: it’ll be a new moon.
During this time, the moon is at the closest to the Earth than at any other time making it appear 14 percent bigger and 30 percent brighter than other full moons.
Scientists call this phenomenon a “perigee moon.” The moon is usually about 238,000 miles from our planet, but because of the elliptical shape of the moon’s orbit, the distance varies throughout the year. At perigee, the moon is about 12,000 miles closer to the Earth.
The moon’s phase and date of its approach to its perigee is not synced, but sometimes it’s possible for a full moon to occur at the same time. This is what’s known as a supermoon.
You won’t be able to see Wednesday’s unique supermoon due to the sun’s glaring rays concealing it during day hours. But with minimal light pollution from the moon, it’ll be a prime time to dig out those astronomical binoculars and go searching for faint objects in the galaxy.
