PN7 has been a mysterious space traveler, shadowing our planet for decades undetected in our vast celestial world, until now.

It’s hard to believe, but some reports circulating on social media say there are two moons and there will be for several decades. One is the normal moon that we see most nights. But the other — 2025 PN7 — is considered a quasi-moon, ABC News reported.

Was a new moon discovered? What is the name of the new moon? What is a Quasi-moon? Does the Earth have two moons? An expert explains it all.

It sounds like a sci-fi plot, but it’s a cold, hard scientific fact: our closest cosmic neighbor, the moon, is slowly moving farther from Earth. Is this a big deal? And if so, how does it affect life here on our planet?

The next full moon will be the closest supermoon of 2025, set to shine for days. Here's when to watch and what to know about November's beaver moon.
