2022 FD1

April 11, 2024

2022 FD1 is a small, metre-sized Apollo near-Earth asteroid that was eclipsed by Earth 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]

2022 FD1 was discovered on 24 March 2022, by astronomer Krisztián Sárneczky at Konkoly Observatory's Piszkéstető Station in Budapest, Hungary.[2] It was his next near-Earth asteroid discovery after the impactor 2022 EB5 from early March 2022.[3]

Notes edit

  1. ^ Earth has a radius of 6,371 km and 2022 FD1 nominally passed about 14,845+8
    −7     km     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)
