2017-12-03: Supermoon ⬅︎
This year has only one Supermoon -- December 3, 2017.

What is a supermoon? Technically, it is when the moon is within 224,641 miles of earth at a full moon. Keep in mind that the moon orbits the earth in a path that is elliptical, not circular. When it is at perigee, the closest point in its orbit, it can be as close as 221,500. And when it is at apogee, the furthest point in its orbit, it can be as far as 252,700 miles. Any time the moon is no further than 224,641 miles from earth at full moon, it is called a supermoon and will appear slightly larger.

The term supermoon is not a scientific term. Instead, scientists use the term perigee full moon but supermoon, of course, is a lot catchier.

Whatever you'd like to call it, hopefully you got a chance to see it!
