 is a small and harmless near-Earth object that will pass within 0.014 AU of Earth around 17 December 2024. At 17 December 2024 06:14 UT it has a 0.23% (1-in-430) chance of impacting Earth. It is estimated to be 3-meters in diameter which would make an impact comparable to. It has a very short observation arc of 0.4 days and was first imaged on 17 December 2022 07:07 when it was 0.004 AU from Earth.

At the time of the virtual impactor (17 December 2024 06:14) the asteroid is expected to be 0.0055 AU from Earth but has an uncertainty region of ±1.5 e6km. The nominal approach to Earth is expected to occur about nine hours later at 17 December 2024 15:41 at a distance of 0.005 AU.

It will come to perihelion (closest approach to the Sun) on 30 January 2023.
