“It's not really very unusual,” said Derrick Pitts, chief astronomer with the Franklin Institute in Philadelphia.

Everyone in the world can see a supermoon without special equipment if clear skies permit. But the difference can be tough to discern, especially if people haven’t observed the regular moon on the nights leading up.

“If you go out and just look at the moon when it’s very high in the sky, there is nothing relative to it to give you an idea of how big it looks,” Pitts said.

In the latest viewing, the moon will pass within about 224,600 miles of Earth. The closest supermoon of the year is slated for November, followed by another in December.

The spectacles continue in 2026 with two lunar eclipses: a total eclipse across much of North America, Asia and Australia in March, and a partial one in August across the Americas, Africa and Europe.
