Nakano Note (Nakano wa Kangaeru noda) NK 5456 C/2024 Q3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 78 observations 2024 July 29 to 2025 June 13. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.36 arc second. The comet will pass 2.41 AU from Jupiter on 2027 Jan. 28 UT. See an orbit in CBET 5440 (= CH 2025). Epoch = 2025 Feb. 14.0 TT T = 2025 Mar. 5.22122 +/- 0.00043 (m.e.)
