2012 KP24 (also written 2012 KP24) 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.[2] Around 31 May 2023 ±3 days it will pass between 0.19–24 lunar distances (73,000–9,200,000 km) from Earth.[2] Nominally the asteroid is expected to pass 0.026 AU (3,900,000 km; 10 LD) from Earth and brighten to around apparent magnitude 21.6.[5]

It is a fast rotator that rotates in 0.04 hours (2.4 min).[2] The asteroid is estimated to be 17 meters (56 ft) in diameter.[3] It will next come to perihelion (closest approach to the Sun) around 4 July 2023.[2] It has an orbital uncertainty parameter of 6.[2]
