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]
