Nakano Note (Nakano wa Kangaeru noda) NK 5382 C/2024 Q4 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 38 observations 2024 Aug. 31 to 2025 Jan. 23. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.27 arc second. The comet has passed 1.17 AU from Neptune on 2009 Nov. 13 and 1.95 AU from Jupiter on 2024 Apr. 13 UT. Due to these close approaches comet will be made a long periodic comet of P= about 5000 years.
