軌道要素The following improved orbital elements by Kenji Muraoka, are from 52 observations 1983 May 8 to 1998 June 18, perturbations by 9 Plantes, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.63 arc seconds. Epoch = 1998 Nov. 3.0 TT JDT = 2451120.5 T = 1998 Nov. 18.85374 +/- 0.00132 (m.e.)
