Earth is set to gain another moon by the end of the month — a small asteroid that will be snared by our planet's gravity until the end of the year, scientists say.
The mini-moon, an asteroid called 2024 PT5, was spotted by the Asteroid Terrestrial-Impact Last Alert System (ATLAS) on Aug. 7. The space rock will make one complete orbit of our planet between Sept. 29 and Nov. 25 before escaping Earth's gravity.
