2020 VT1

{{mp|2020 VT|1}} was discovered on 10 November 2020, by J. Bulger, K. Chambers, T. Lowe, A. Schultz, and M. Willman observing

for the survey conducted by Pan-STARRS at Haleakalā Observatory, Hawaii. As of 20 January 2021, it has been observed 28 times with an observation arc of 24 days.

{{mp|2020 VT|1}} is currently an Amor asteroid, a subgroup of the near-Earth objects that approach the orbit of Earth from beyond, but do not cross it. It orbits the Sun at a distance of 1.3–1.8 AU once every 23 months (687 days; semi-major axis of 1.52 AU). Its orbit has a moderate eccentricity of 0.17 and an inclination of 19° with respect to the ecliptic. It is most notable for its horseshoe orbit, a complex co-orbital motion with Mars, as both bodies have similar semi-major axes. The object can also be classified as a Mars-crosser, intersecting the orbit of the Red Planet at 1.66 AU.
