Asteroid 2025 TF flew just 420 km (260 miles) above Antarctica, second-closest flyby on record

2025年10月2日 11:06
A newly-discovered asteroid designated 2025 TF made an extremely close approach to Earth at 00:49 UTC on October 1, 2025, reaching a nominal distance of 0.02 LD (0.00005 AU / 6 790 km / 4 220 miles) from Earth’s center -- equivalent to about 419 km (260 miles) above the surface over Antarctica. At this distance, it is now classified as the second-closest asteroid flyby ever recorded.
