NEW YORK (AP) — The moon will look slightly bigger and brighter Wednesday night during the closest supermoon of the year.

The moon's orbit around the Earth isn't a perfect circle, so it gets nearer and farther as it swings around. A so-called supermoon happens when a full moon is closer to Earth in its orbit. That makes the moon look up to 14% bigger and 30% brighter than the faintest moon of the year, according to NASA.
