The moon's orbit is egg-shaped, which means that it actually can appear closer or further away depending on where it is in the sky. Its shortest distance from Earth in its roughly month-long lunar cycle is known as perigree. Its furthest distance from Earth, in contrast, is known as apogee. Yet a supermoon doesn't always happen when a moon is at perigree.
"Supermoon" is actually a general term used to describe a full moon that occurs roughly the same time the moon is nearest Earth in its monthly orbit. It's a phrase that has only infiltrated the media relatively recently, coined by an astrologer--not an astronomer, according to EarthSky. Since the moon affects tides, a supermoon can actually cause a high-tide that's a few inches further up the shore than a high-tide during a normal moon, according to NASA.
This weekend's supermoon, which will peak on June 23 at 7:32 a.m., is set to be the closest to Earth it's been all year. The moon will be about 221,824 miles away, which is roughly 30,000 miles closer than it is at its furthest, according to Cnet. Because of this, the moon will appear about 14 percent larger and 30 percent brighter than a typical full moon, according to ABC7. Despite all of the hype, though, a lot of star gazers won't even be able to tell the difference between the supermoon we'll see and a regular full moon.
You'd better enjoy the moon while you can, though. We won't see a larger supermoon than this until September 28, 2015. And the largest supermoon until 2034 will occur on November 14, 2016.
