Earth's New Quasi-Moon: A Decades-Old Cosmic Companion
TL;DR
Astronomers have discovered a tiny asteroid, 2025 PN7, that has been orbiting the Sun in a path similar to Earth's for decades, acting as a quasi-moon for about another 60 years. It is the smallest and least stable of Earth's quasi-moons, and while it occasionally appears to orbit Earth from our perspective, it actually orbits the Sun. Discovered in 2025 but present since at least 1957, it poses no threat and could be useful for future space exploration tests.
