As sky surveys improve, smaller and smaller asteroids are regularly being discovered. The small near-Earth asteroids 2008 TC 3, 2014 AA, 2018 LA, 2019 MO, 2022 EB 5, 2022 WJ 1, 2023 CX 1, 2024 BX 1, 2024 RW 1, 2024 UQ, and 2024 XA 1 are the only eleven asteroids discovered before impacting into Earth (see asteroid impact prediction).
The first asteroid flyby within 1 LD of Earth in 2022 was asteroid 2021 YK (10–20 meters in diameter), which was observed on 27 December 2021 04:40 UT (when it was about 3.8 million km from Earth) and passed 0.49 LD (190 thousand km) from Earth on 2 January 2022. The largest asteroid to pass within 1 LD of Earth in 2022 was 2022 TM 2 with an ...
2022 FD 1 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 ...
An example list of near-Earth asteroids that passed more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2008. 2007 TU 24 (~250 meters in diameter) passed 1.44 LD (554,000 km) from Earth on January 29, 2008. 2008 CE 22 (~18 meters in diameter) passed between 0.9997 and 1.0023 LD (384,300 to 385,300 km) from Earth on February 6, 2008.
2022 EB 5 was a small, two-metre Apollo near-Earth asteroid that disintegrated in Earth's atmosphere at 21:22 UTC on 11 March 2022, over the Arctic Ocean southwest of the Norwegian island Jan Mayen. With an atmospheric entry speed of 18 km/s (11 mi/s), the asteroid's impact generated a 4-kiloton-equivalent fireball that was detected by ...
Asteroid designation Date of impact Location of impact Method of detection Estimated size Reference 2008 TC 3: October 7, 2008: Nubian Desert in Sudan: visual, weather satellite, meteorite recovery: 4 m (13 ft) [1] 2014 AA: January 2, 2014: Central Atlantic Ocean: infrasound: 2–4 m (6.6–13.1 ft) [2] 2018 LA: June 2, 2018: Botswana/South ...
2008 EV 5 started its existence as part of a much larger body in the asteroid belt, with a likely diameter greater than 100 kilometers. [13] 2008 EV 5 's immediate history likely started when its parent body experienced a large cratering event or, more likely, a catastrophic disruption event that resulted in a highly fractured, shattered, or reaccumulated object (rubble pile).
2022 BX 1 is a potentially hazardous asteroid around 200 meters in diameter that was discovered on 25 January 2022 when it was 0.36 AU (54 million km) from Earth. [1] On 29 January 2022 with an observation arc of 22 days it was rated with a Torino scale of 1 for a virtual impactor on 11 July 2061 21:22 UTC. [3]
