(2023 passage) 26.4 2012 KP 24 is a Chelyabinsk-sized near-Earth asteroid with an observation arc of only 5 days and has a modestly determined orbit for an object of its size. Around 31 May 2023 ±3 days it passed between 0.19 - 24 LD km 2 on from Earth. Nominally the asteroid is expected to pass 0.026 AU km LD on on from Earth and brighten to around apparent magnitude 21.6. It is a fast rotator that rotates in 0.04 hour min. The asteroid is estimated to be 17 m us in diameter. It will next come to perihelion (closest approach to the Sun) around 4 July 2023. It has an orbital uncertainty parameter of 6. 2012 It was discovered on 23 May 2012 by the Mount Lemmon Survey at an apparent magnitude of 20.8 using a 1.5 m in on us reflecting telescope. On 28 May 2012 at 15:20 UT, the asteroid passed 0.00038 AU km mi on on from the center-point of Earth. It then reached perihelion on 2 July 2012. It was removed from the Sentry Risk Table on 8 August 2013 after Sentry updated to planetary ephemeris (DE431). 2032 Newer versions of Sentry returned the object to the risk table. Virtual clones of the asteroid that fit the uncertainty region in the known trajectory show a 1 in 2.1 million chance that the asteroid could impact Earth on 2032 May 28. With a Palermo Technical Scale of −6.30, the odds of impact by 2012 KP 24 in 2032 are about 2 million times less than the background hazard level of Earth impacts which is defined as the average risk posed by objects of the same size or larger over the years until the date of the potential impact.
