2021 EU (original) (raw)

2021 EU is a small near-Earth object that should pass within 0.4 AU (60 million km) 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 (34 million km) from Earth. On 27 February 2024 it is nominally expected to be 0.09 AU (13 million km) from Earth but has an uncertainty region of ±45 million km (0.30 AU). The nominal 2024 Earth approach would have the asteroid only brightening to apparent magnitude 23 near closest approach.
