C/2020 S4 PanSTARRS
more info
Comet C/2020 S4 was discovered on 16 September 2020, about 2.5 yr before its perihelion passage. 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 2.40 yr in a range of heliocentric distances from 8.04 au to 3.37 au.

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