Nakano Note (Nakano wa Kangaeru noda) NK 5187 P/PANSTARRS (2014VF 40)
The following improved orbital elements, by S. Nakano, are from 66 observations 2014 to 2024. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.39 arc second. See an orbit in CBET 5359 (same orbit).
