Astronomers confirm a tiny new moon is orbiting Earth, and it'll stick around for the holidays
This extraterrestrial traveler is expected to stick around until January 2027, extending its stay through the holidays before breaking free of our planet's influence.
- Astronomers now think Earth grabs minimoons pretty frequently; we are likely to have at least one at any given time.
- Most of the space rocks stay around for less than a year, although a handful may remain in Earth's gravitational pull for decades.
- In April, our planet picked up a passing "minimoon," pulling the space rock into a temporary orbit, astronomers have confirmed.
However, researchers don't think there is much chance of that happening, since 2026 QQ8 is currently orbiting at around 1.5 times the average distance of the moon.
Large Aten asteroids are considered the most dangerous type of asteroid, as they can easily get lost in the sun's glare before speeding toward Earth — but, again, our new mini companion is far too small to pose a threat.
- That distinction belongs to 1991 VG, which was around 30 feet (10 meters) in diameter when it was detected in November 1991.
- This minimoon is classified as an Aten asteroid; this population of space rocks occasionally cross into Earth's orbit and have semimajor axes smaller than Earth's, meaning they typically orbit closer to the sun than our planet does.
- The Rubin observatory, which takes a full scan of the entire Southern Hemisphere sky every few days, has already spotted what may be a new dwarf planet lurking in the outer solar system, as well as a new satellite galaxy of the Milky Way.
- It was officially reported by the International Astronomical Union's (IAU) Minor Planet Center — the body that logs and confirms new solar system objects — on Oct.
- If it got too close to Earth, it would likely burn up in our planet's atmosphere.
