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]
Orbit and classification
It orbits the Sun at a distance of 0.6–3.5 AU once every 2 years and 11 months (1,073 days; semi-major axis of 2.05 AU). Its orbit has an eccentricity of 0.71 and an inclination of 6° with respect to the ecliptic.[2]
