2002 NY40 is a sub-kilometer near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 800 meters (2,600 feet) in diameter.[1] The contact binary with a bilobated, peanut-like shape was first observed on 14 July 2002 by the LINEAR automated system in New Mexico. On 18 August 2002, it passed Earth at a distance of 540,000 km.[3] It was observed with adaptive optics by the Midcourse Space Experiment.[4]
