2021 EU

2021 EU is a small near-Earth object that should pass within 0.4 AU of Earth in 2024. On 27 February 2024 it has a 1-in-32,000 chance of impacting Earth. It is estimated to be 28-meters in diameter which would make it larger than the Chelyabinsk meteor. It has a short observation arc of 15 days and has not been observed since 17 March 2021 when it was 0.23 AU from Earth. On 27 February 2024 it is nominally expected to be 0.09 AU from Earth but has an uncertainty region of ±45 e6km. The nominal 2024 Earth approach would have the asteroid only brightening to apparent magnitude 23 near closest approach.

The nominal orbit has it come to perihelion (closest approach to the Sun) on 8 January 2024 and then pass 0.075 AU from Earth on 22 February 2024.
