The "Beaver" Full Moon: Closest Supermoon of the Year
On Wednesday evening, a supermoon known as the "beaver" full moon will rise in the eastern sky, marking the nearest supermoon of the year. Though the difference from other full moons won't be striking to the naked eye, you can improve your viewing experience by choosing the right time and location.
When and How to Watch the Supermoon
The optimal time to observe the supermoon is just as it rises above the horizon, around sunset. Face east with your back to the setting sun, ideally from a spot offering a clear horizon and free of clouds.
What Is a Supermoon?
The term "supermoon" refers to a full moon that appears closer to Earth than usual. This occurs because the Moon's orbit around Earth is elliptical, not circular, meaning its distance varies.
- At its nearest point, called perigee, the Moon is closer to Earth.
- At its farthest point, called apogee, the Moon is farther away.
A full moon occurring within 90% or less of its perigee distance is dubbed a supermoon.
Other Related Terms
When a full moon coincides with apogee, it is known as a micromoon.
"The Moon doesn't orbit around the Earth in a perfect circle — it's more of an oval-shaped orbit."
