    2010 JL88 is a small Near-Earth object on the lower part of the Sentry Risk Table.[1] It was discovered on May 15, 2010 and is known to have an unusually rapid rotation of about 24.5 seconds.[3][7] On May 17, 2010, it passed 0.00257 AU (384,000 km; 239,000 mi) from Earth.[3]

    Earth impact possibility

    2010 JL88 has an Earth minimum orbit intersection distance of 0.45 Lunar Distances[8] However, it only has a 1 in 1,449,000 (0.000069%) chance of impacting into Earth sometime after 2049.[1] Even if it did impact, 2010 JL88 is so small that it would simply disintegrate in a manner similar to the Chelyabinsk meteor.[9]

    Rotation

    2010 JL88 rotates at an extremely rapid rate of 24.5 seconds. 2010 JL88 is the second fastest natural rotating object discovered in the Solar System, after 2014 RC.[7] The asteroid was found to have a rapid rotation by the Magdalena Ridge Observatory's 2.4-meter telescope.
