Abstract

The article discusses the existence of quasi-moons and temporary moons that orbit Earth, highlighting the recent discovery of a new quasi-moon named 2025 PN7. While Earth is commonly thought to have only one Moon, there are other small celestial bodies that can temporarily or quasi-orbit our planet. Quasi-moons, such as Cruithne and 2025 PN7, share similar orbital periods with Earth but do not have closed orbits around it. The article notes that 2025 PN7, discovered by the Pan-STARRS observatory, is 19 meters in diameter and can come as close as 186,000 miles to Earth, making it a notable addition to the list of Earth's mini-moons.
