The Non-gravitational Parameters of the Hyperbolic Comet 2I/Borisov

Ireneusz Wlodarczyk

aWe computed the non-gravitational parameters of the comet 2I/Borisov for different astrometric error models. We used all 3092 optical observations from 2018 December 13.47655 to 2020 April 28.447219. The difference between the obtained values of non-gravitational parameters A₁, A₂, and A₃ using different methods of selection and weighting of observations is so small that the orbit is still hyperbolic.
