    Discovery

    2020 OV1 was discovered at r=20.2 mag on 2020 July 19 by the Zwicky Transient Facility using the 1.2-m f/2.4 Schmidt.[3]

    Orbit and classification

    It orbits the Sun at a distance of 0.5–0.8 AU once every 6 months (186 days; semi-major axis of 0.64 AU). Its orbit has an eccentricity of 0.25 and a relatively high inclination of 33° with respect to the ecliptic.[2]

    The orbital evolution of 2020 OV1 indicates that it is comfortably entrenched within the Atira orbital realm, but it might have arrived there relatively recently.[4]
