Earth Has a New Temporary Mini-Moon: Meet 2025 PN7
Asteroid 2025 PN7, discovered in 2025, will orbit Earth as a quasi-moon for 58 years before leaving in 2083, marking a rare long-term co-orbital companion.
- On Aug. 2, 2025, scientists at the Pan‑STARRS observatory discovered 2025 PN7, which NASA simulations identified as a quasi‑moon sharing Earth's orbit.
- Researchers estimate the object has been near Earth for around 60 years, likely slipping into its current orbit around 1957.
- Measuring about 19 metres wide and no larger than 52 feet, 2025 PN7 is too small and faint to see without powerful telescopes.
- Researchers say the rock poses no danger to Earth, and NASA confirms 2025 PN7 does not threaten Earth while offering clues to solar system evolution.
- Amid online rumours, experts clarified Earth has one natural satellite and hosted quasi-moons like Kamo'oalewa, while Carlos de la Fuentes said `No real hints about its origins, only speculations`.
