2025 PU is a near-Earth asteroid belonging to the Apollo group. It has a estimated diameter of 2.1–4.8 meters.[3]
On 2 August 2025, 2025 PU made a close approach to Earth, passing within 53,000 kilometers of Earth with a speed of 10.5 kilometres per second (6.5 mi/s). This makes it the 83rd asteroid to fly within the orbit of the Moon in 2025, and the first asteroid to do so in the month of August.[3][4] 10 hours after closest approach, on 3 August, it was first observed by the NASA/JPL SynTrack Robotic Telescope in Auberry, California, United States.[3] It was given the provisional designation 2025 PU by the Minor Planet Center, and its detection was announced in a Minor Planet Electronic Circular on 4 August.[5]
