Asteroid , about the size of a school bus at 33 feet (10 meters), was first spotted in August by astronomers at . It will join Earth's orbit from September 29 to November 25, 2024, as a temporary "mini moon".
The asteroid's discovery was made using a powerful telescope in , highlighting the increasing capability of survey instruments to detect such small and elusive space rocks.
Observation and Future Trajectory
While not visible to the naked eye or through amateur telescopes, 2024 PT5 can be observed with large, research-grade telescopes. It will orbit Earth for nearly 57 days without completing a full orbit.
After its brief stay, 2024 PT5 will continue its journey through space, expected to return in 2055. This event underscores the rarity and fascinating nature of mini moons, with 2024 PT5 being a short-capture example.
