Nakano Note (Nakano wa Kangaeru noda) NK 5402 P/2023 RS61
The following improved orbital elements, by S. Nakano, are from 67 observations 2015 Sept. 5 to 2024 Dec. 2. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.29 arc second. See an orbit in CBET 5539 (same orbit). Epoch = 2028 Dec. 15.0 TT T = 2028 Dec. 10.48389 +/- 0.01732 (m.e.)
