Nakano Note (Nakano wa Kangaeru noda) NK 5532 C/2025 V2 (Rankin)
The following improved orbital elements, by S. Nakano, are from 83 observations 2024 Nov. 29 to 2025 Dec. 14. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.49 arc seconds. The comet will pass 2.37 AU from Jupiter on 2026 Mar. 8 UT. See an orbit in CBET 5639 (= NK 5490). Epoch = 2027 Mar. 16.0 TT T = 2027 Mar. 23.08307 +/- 0.02102 (m.e.)
