C/2020 V2 ZTF
more info
Comet C/2020 V2 was discovered on 2 November 2020, about 2.5 yr before its perihelion passage; later a series of prediscovery images was found going back to 18 April 2020 (10.08 au from the Sun). In the moment of orbit determination, this comet was still observed.

Currently, solutions (GR and NG) based on pre-perihelion data are given. Therefore, the data arc span over 3.0 yr in a range of heliocentric distances from 10.08 au to 2.24 au.Orbits based on a distant part of data arc are also given (helicentric distances greater than 3.5 au).

This is Oort spike comet. According to orbits obtained using pre-perihelion data this comet suffers rather small planetary perturbations that lead to escape this comet from the solar system on hyperbolic orbit.
