Nakano Note (Nakano wa Kangaeru noda) NK 4984 C/2022 JK5 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 63 observations 2022 May 9 to 2023 Apr. 24. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.34 arc seconds. The comet will pass 2.48 AU from Jupiter on 2024 June 14 and 2.91 AU from Uranus on 2031 July 10 UT. See an orbit in CBET 5246 (same orbit).
