C/2021 T2 Fuls
more info
Comet C/2021 T2 was discovered on 2 October 2021 by Mt. Lemmon Survey, that is about eight months before its perihelion passage. this comet was observed only until 25 February 2022.
Comet had its closest approach to the Earth on 6 July 2022 (1.14 au), about one month after its perihelion passage.
Therefore, the GR solution given here is based on preperihelion data span over 0.400 yr in a range of heliocentric distances from 3.52 au to 1.96 au.
This Oort spike comet suffers tiny planetary perturbations during its passage through the planetary system that likely lead to escape this comet from the solar system on a marginally hyperbolic orbit.
