Orbital Elements The following improved orbital elements by Kenji Muraoka, are from 160 observations 1998 Apr. 22 to Dec. 27, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.56 arc seconds. Epoch = 1998 Aug. 15.0 TT JDT = 2451040.5 T = 1998 Sept. 1.01935 +/- 0.00334 (m.e.) TT Peri. = 165.24641 +/- 0.00085 Node = 18.25555 +/- 0.00066 (2000.0) Incl. = 35.63678 +/- 0.00026 q = 3.4166407 +/- 0.0000219 AU e = 0.9451411 +/- 0.0000595 1/a = +0.0160564 +/- 0.0000174 1/AU ( P = 492 years )
