C/2022 T1 Lemmon
more info
Comet C/2022 T1 was discovered on 3 October 2022 with the Mt. Lemmon Survey, that is a year and more than four months before its perihelion passage.
Comet had its closest approach to the Earth on 23 April 2024 (2.51 au), about two months after its perihelion passage.
GR solution given here is based on data span over 1.77 yr in a range of heliocentric distances: 5.60 au – 3.44 au (perihelion) – 3.69 au.
This Oort spike comet suffers smalll planetary perturbations during its passage through the planetary system that lead to escape this comet from the solar system on a hyperbolic orbit.
