Earth has a new quasi-moon, and it's an asteroid
Scientists have discovered that Earth has picked up a new "quasi-moon"—an asteroid called 2025 PN7.
Discovered on August 29, 2025, by the Pan-STARRS survey in Hawaii, this rock is roughly the size of a small office building and shares our orbit, but it's not actually stuck to us like the real Moon.
Asteroid will part ways with us around 2083
2025 PN7 has been tagging along with Earth for an estimated 60 years and will keep us company until about 2083 before drifting away.
It's one of seven known quasi-moons cruising near our planet right now.
Researchers can study these temporary moons to understand solar system
Sadly, you'll need a seriously big telescope to spot this one—it's way too faint for the naked eye and doesn't mess with tides or anything here on Earth.
But for researchers, these temporary moons are a cool way to study how small objects move around our planet over decades, helping us better understand how things work in our solar system.
