Earth has a new temporary visitor, known as a “mini-moon.” The asteroid 2024 PT5 has entered Earth’s gravity and will orbit our planet until November 25. This is the fifth mini-moon recorded. Discovered by former ISRO scientist Manish Purohit, 2024 PT5 is about 10 meters (33 feet) wide and comes from the Arjuna asteroid belt. While it won’t orbit Earth like the moon, it will follow a horseshoe-shaped path for about 55 days before escaping back into space, providing astronomers a chance to study it.
