Orbital Elements The following improved orbital elements by Kenji Muraoka, are from 120 observations 2001 Jan. 7 to Mar. 18, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.76 arc seconds. Epoch = 2000 Sep. 13.0 TT JDT = 2451800.5 T = 2000 Sep. 17.59987 +/- 0.00685 (m.e.) TT Peri. = 107.87879 +/- 0.00522 Node = 339.59578 +/- 0.00113 (2000.0) Incl. = 59.93876 +/- 0.00209 q = 2.4062828 +/- 0.0001452 AU e = 0.9909158 +/- 0.0000835 1/a = +0.0037752 +/- 0.0000347 1/AU ( P = 4311 years )
