Discovery
2020 VT1 was discovered on 10 November 2020 by J. Bulger, K. Chambers, T. Lowe, A. Schultz, and M. Willman observing for the Pan-STARRS Survey.[7] As of 20 January 2021, it has been observed 28 times with an observation arc of 24 days.[2]
Orbit and orbital evolution
2020 VT1 is currently an Amor asteroid. Its semi-major axis (currently 1.5231 AU) is similar to that of Mars (1.52380 AU), but it has a low value of orbital eccentricity (0.16702) and moderate orbital inclination (18.717°).[6]
