軌道要素The following improved orbital elements by Kenji Muraoka, are from 185 observations 1984 to 1998, including 9 Planets, Moon and 5 minor planets perturbations and non-gravitational effect of style II. The mean residual is +/- 0.72 arc seconds. Epoch = 1997 Sept. 29.0 TT JDT = 2450720.5 T = 1997 Sept. 29.21665 +/- 0.00080 (m.e.)
