C/2022 K1 Leonard
more info
Comet C/2022 K1 was discovered on 30 May 2022 by Mt. Lemmon Survey, that is about 5.5 months after its perihelion passage.
Comet had its closest approach to the Earth on 27 July 2022 (3.43 au), about 7.5 months after its perihelion passage. however, on the pre-perihelion leg of orbit it had approach to Earth within 3.56 au (24 June 2021).
Thus, the GR solution given here is based on post-perihelion data span over 0.323 yr in a narrow range of heliocentric distances from 4.23 au to 4.65 au.
This Oort spike comet suffers tiny planetary perturbations during its passage through the planetary system.
