軌道要素The following improved orbital elements by Kenji Muraoka, are from 244 observations 1931 to 2000, perturbations by 9 Plantes, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.94 arc seconds. Epoch = 1999 Aug. 10.0 TT JDT = 2451400.5 T = 1999 Aug. 25.13062 +/- 0.00014 (m.e.)
