C/2019 Q3 PanSTARRS
more info
Comet C/2019 Q3 was discovered on 29 August 2019, about 10.5 months after its perihelion passage; later a series of prediscovery images was found going back to 3 July 2019. This comet was observed only to 6 September 2019.

Thus, the solution given here is based on post-perihelion data and span over 0.178 yr in a range of heliocentric distances from 7.53 au to 7.65 au.

This comet seems to be Oort spike comet with a bit tight future orbit than original orbit; however original and future semimajor axis is poorly known (see uncertainties of barycentric orbits).
