Researchers from Spain have discovered a kind of second moon orbiting around Earth. Known as Apollo asteroid 2025 PN7, it was detected by the Pan-STARRS observatory in Hawaii on August 2nd, 2025. According to current calculations, it has been accompanying the Earth since the 1960s—and it’s expected to stay that way for the next 60 years.

However, it must be said that 2025 PN7 is not a real moon but rather something called a quasi-moon . A quasi-moon is an asteroid that orbits around the sun but in such a way that it looks like it’s orbiting around a planet from the perspective of that planet. In this case, 2025 PN7 looks like it’s orbiting Earth but isn’t bound by Earth’s gravitational pull.

2025 PN7’s behavior is consistent with those in the Arjuna asteroid belt, which are a group
