軌道要素The following improved orbital elements by Kenji Muraoka, are from 117 observations 1980 to 1998, including 9 Planets, Moon and 5 minor planets perturbations and non-gravitational effect of style II. The mean residual is +/- 0.70 arc seconds. Epoch = 1998 Nov. 3.0 TT JDT = 2451120.5 T = 1998 Oct. 14.14962 +/- 0.00182 (m.e.)
