Earth Will Have a Temporary 'Mini Moon' for Two Months

Exciting news from space! Earth is about to capture a "mini moon" — but only for a brief period. This isn't another natural satellite like our familiar moon. Instead, it's an asteroid, specifically named 2024 PT5, which will be temporarily trapped by Earth's gravitational pull. Measuring about 33 feet (10 meters), roughly the size of a school bus, this asteroid was first spotted in August 2024 by astronomers from Complutense University of Madrid using a telescope in South Africa. It will begin its brief orbit around Earth starting September 29, 2024, and will remain with us for approximately two months.

Interestingly, these mini moons are not a rare phenomenon, though they are usually hard to detect due to their small size and brief stay in Earth's orbit. According to astronomers like Richard Binzel from MIT, Earth has captured such objects before, though this is only the third time a "long-capture" event has been documented. The previous one occurred in 2020. Thanks to modern advancements in observational technology, we are now able to spot these fascinating space rocks more routinely.

Despite its intriguing presence, 2024 PT5 won’t be visible to the naked eye. It’s far too small for amateur telescopes, but professional astronomers using high-grade equipment will be able to observe it. The asteroid is part of a group of near-Earth objects from the Arjuna asteroid belt, which orbits the Sun in a path similar to Earth's. However, it won’t stay with us long enough to complete a full orbit before it leaves Earth's gravitational grip on November 25, 2024.

This rare celestial event reminds us of the dynamic nature of space. Though 2024 PT5 will drift away after its brief visit, it may return for another flyby in 2055, providing astronomers another opportunity to study such phenomena. These mini moons offer us valuable insights into how Earth's gravity interacts with nearby space objects, contributing to our understanding of both asteroid behavior and Earth's place in the vast universe.
