Orbital Elements The following improved orbital elements by Kenji Muraoka, are from 50 observations 2001 Jan. 21 to Apr. 4, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.56 arc seconds. Epoch = 2001 Jan. 11.0 TT JDT = 2451920.5 T = 2001 Jan. 30.40098 +/- 0.02265 (m.e.) TT Peri. = 189.33467 +/- 0.02647 Node = 355.81726 +/- 0.02832 (2000.0) Incl. = 10.61806 +/- 0.00050 q = 2.3468806 +/- 0.0007246 AU e = 0.5869378 +/- 0.0000897 a = 5.6816641 +/- 0.0012474 AU n = 0.07277643 +/- 0.00002397 P = 13.543 +/- 0.0044600 years (+/- 1.63 days)
