US EditionEarth 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'.

The celestial object, with which it has given the University of Hawaii and which has been baptized with the unattractive name of 2025 PN7, will serve scientists.
The Earth Two Moon Theory Is Real - But Is It Dangerous? Here Are Possible Scenarios If Quasi Celestial Body Starts Affecting Us
The idea that Earth might have a second moon has long fascinated astronomers and captivated online audiences, with viral posts and speculative blogs fuelling claims of a mysterious celestial companion. Scientific observations show that Earth does not possess a stable second moon, though astronomers have identified smaller objects known as quasi-satellites and 'minimoons' that share its orbit or are briefly captured by its gravity. These faint co…
NASA has detected a new asteroid that has been traveling with Earth since the 1960s, acting like a second moon. It will be with us until 2083 before it leaves.
