2022 YO1

Risk–listed near-Earth asteroid

2022 YO1 is a small and harmless near-Earth object that will pass within 0.014 AU (2.1 million km) of Earth around 17 December 2024.[3] At 17 December 2024 06:14 UT it has a 0.23% (1-in-430) chance of impacting Earth.[2] It is estimated to be 3-meters in diameter which would make an impact comparable to 2008 TC3. 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 (600 thousand km) from Earth.

At the time of the virtual impactor (17 December 2024 06:14) the asteroid is expected to be 0.0055 AU (820 thousand km) from Earth but has an uncertainty region of ±1.5 million km (0.01 AU).[5] 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 (750 thousand km).[3]
