Nakano Note (Nakano wa Kangaeru noda) NK 4807 A/2021 X2
The following improved orbital elements, by S. Nakano, are from 51 observations 2021 Oct. 30 to 2022 Aug. 23. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.24 arc second. The object will pass 2.57 AU from Jupiter on 2022 Oct. 28 UT. See the previous orbit in NK 4664. Epoch = 2022 June 30.0 TT T = 2022 July 8.15750 +/- 0.00085 (m.e.)
