From Wikipedia, the free encyclopedia
2025 TF, previously known as C15KM95, is a meter-sized near-Earth asteroid that passed 409 ± 14 km (254 ± 9 mi) over the surface of Earth's South Pole (Antarctica) on 1 October 2025 00:49 UTC, at a relative speed of 20.9 km/s (13.0 mi/s).[a] It is the third-closest asteroid flyby of Earth recorded as of 2025[update], after 2025 UC11 and 2020 VT4.[6][4][7] 2025 TF was discovered on 1 October 2025 06:36 UTC by astronomers using the Bok Telescope at Kitt Peak National Observatory in Arizona, less than 6 hours after the asteroid's closest approach to Earth.[2][6]
