The asteroid's provisional designation as a minor planet, "2024 YR 4", was assigned by the Minor Planet Center when its discovery was announced on 27 December 2024. [2] The first letter, "Y", indicates that the asteroid was discovered in the second half-month of December 2024 (16 to 31 December), and "R 4" indicates that it was the 117th provisional designation to be assigned in that half-month.
The asteroid with the greatest chance of impacting Earth in 2025 is 2009 VA (6-meters in diameter) with less than a 1-day observation arc. [8] It has a 1:48,000 chance of impact on 06 November 2023, but is expected to be around 0.3 AU (45 million km ) from Earth on that date with uncertainty region of ± 900 million km. [ 10 ]
