2020 HA10 is a near-Earth object of the Atira group. It was discovered at G=20.4 mag on 2020 April 28 by the Mount Lemmon Survey using the 0.5 m reflector + 10 K CCD.[3]
2020 HA10 orbits the Sun at a distance of 0.7–0.9 AU once every 9 months (271 days; semi-major axis of 0.82 AU). Its orbit has an eccentricity of 0.15 and an unusually high inclination of 50° with respect to the ecliptic.[2] The orbital evolution of 2020 HA10 leads the object into the Aten orbital realm periodically.[4]
