On August 7, 2024, NASA’s Asteroid Terrestrial-impact Last Alert System (ATLAS) detected a space object that, for a little more than a month, will become a mini-moon of Earth. Named 2024 PT5, the rock is only 33 meters long and will form a kind of horseshoe-like orbit around Earth from September 29 to November 5 before leaving Earth’s orbit.

The bus-size asteroid, which was discovered on August 7 by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS), will be sucked in by Earth’s gravitational pull from September 29 to November 25, USA Today reported. During this interstellar layover, the space rock will likely become a “temporary mini-moon,” per Marcos.
