Earth has picked up a new traveling companion – an asteroid named 2025 PN7 that now moves through space in step with us. This tiny quasi moon, only about 62 feet (19 meters) wide, follows an orbit so similar to Earth’s that it will linger nearby for nearly six decades, staying with us until around 2083.

For the next half-century, Earth will have a new celestial companion. A small asteroid, officially designated 2025 PN7, has been confirmed as a quasi-satellite—a rare type of near-Earth object that shares our orbital path around the Sun without being gravitationally bound to our planet.
