Nakano Note (Nakano wa Kangaeru noda) NK 5031 P/2019 S3 (PANSTARRS)
The following improved orbital elements, by S. Nakano, are from 63 observations 2019 Aug. 27 to Nov. 2. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.50 arc second. See an orbit in CBET 4674. Epoch = 2019 Aug. 25.0 TT T = 2019 Aug. 26.09259 +/- 0.00300 (m.e.) TT Peri. = 212.94804 +/- 0.00184 Node = 150.17104 +/- 0.00040 (2000.0) Inc. = 8.69276 +/- 0.00008 q = 1.8067916 +/- 0.0000082 AU e = 0.4706370 +/- 0.0000129 a = 3.4131427 +/- 0.0000843 AU n' = 0.15630483 +/- 0.00000579 P = 6.306 +/- 0.0002337 years (+/- 0.09 day) The predicted orbit for the 2025 return is as follows: Delta-T mightbe more large than m.e. of Period.
