Nakano Note (Nakano wa Kangaeru noda) NK 2851 235P/LINEAR
The following improved orbital elements, by T. Kobayashi, are from 132 observations 2001 to 2010. Perturbations by Mercury to Neptune and three minor planets, Ceres, Pallas and Vesta, were taken into account. The mean residual is +/- 0.75 arc second. See the previous orbit in NK 1894 (= HICQ 2010). Epoch = 2010 Mar. 25.0 TT T = 2010 Mar. 21.88973 +/- 0.02628 (m.e.)
