2022 FD1 is a small, metre-sized Apollonear-Earth asteroid that was eclipsedbyEarth and made its closest approach 8,470 km (5,260 mi) from Earth's surface on 25 March 2022.[a] It entered Earth's shadow at 8:10 UTC and became invisible until egress at 8:45 UTC.[5] Its brightness from Earth reached a peak apparent magnitude of 13 shortly before closest approach at 09:13 UTC.[6] By that time, the asteroid was moving at a speed of 18.5 km/s (11.5 mi/s) relative to Earth and was located in the far Southern hemisphere sky.[4][6]
^Earth has a radiusof6,371 km and 2022 FD1 nominally passed about 14,845+8 −7km from the center of Earth. The asteroid's distance from Earth's surface at closest approach is the difference between the asteroid closest approach radius and Earth's radius. (14,845 – 6,371 = 8,474)
