Nakano Note (Nakano wa Kangaeru noda) NK 2035 P/2010 D2 (WISE)
The following improved orbital elements, by S. Nakano, are from 39 observations 2010 Feb. 25 to 2011 Jan. 30. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.79 arc second. See an orbit on HICQ 2010/2011. Epoch = 2010 Mar. 25.0 TT T = 2010 Mar. 5.14385 +/- 0.01980 (m.e.)
