2020 OV₁ is a near-Earth object of the Atira group. It 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] As of 2023, this minor planet has neither been numbered nor named by the Minor Planet Center.

2020 OV₁ 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]
