C/2021 Q6 PanSTARRS    
    more info
  
        Comet C/2021 Q6 was discovered on 22 August 2021 with the Pan-STARRS 1 telescope (Haleakala), that is two years and seven months before its perihelion passage. 
Comet had its closest approach to the Earth on 2 September 2024 (7.76 au), about half a year after its perihelion passage.
Preferred GR solution given here is based on data span over 3.81 yr in a range of heliocentric distances: 10.99 au – 8.71 au (perihelion) – 8.80 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.
