Nakano Note (Nakano wa Kangaeru noda) NK 5578 C/2024 N1 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 55 observations 2024 June 6 to 2026 Feb. 27. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.57 arc second. The comet has passed 0.47 AU from Saturn on 2022 Sept. 14 and will pass 2.37 AU from Jupiter on 2027 June 11 UT. See the previous orbits in CBET 5410, NK 5312 and NK 5453.
