Unlike the Moon, which is gravitationally bound to our planet, 2025 PN7 shares an orbit around the Sun that closely mirrors Earth's path.

The asteroid isn’t a second moon, instead it is a quasi-satellite that is trailing the Earth’s orbit around the sun. Unlike the moon, 2025 PN7 does not orbit the Earth directly, rather it is a co-orbital object that follows a very similar orbit around the sun as the Earth’s, according to the paper.

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.

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

It may sound like a sci-fi headline but it's very real -- Earth now has a new celestial companion, a little asteroid named Arjuna 2025 PN7 by scientists. NASA has confirmed that the rock, discovered by the University of Hawaii, is officially a “quasi-moon” — a rare type of celestial companion that travels almost exactly in sync with Earth.

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?
