Earth has a second moon

Earth will have a second moon for about two months when a small asteroid, named 2024 PT5, orbits the planet. The asteroid, discovered in August, will revolve around Earth in a horseshoe shape for around 56.6 days. While other non-Earth objects (NEOs) have entered our orbit before, some don't complete full revolutions of the planet, and those that do become mini-moons. An asteroid called 2022 NX1 became a mini-moon in 1981 and 2022, and will return again in 2051.
