Profile

Orbital Elements The following improved orbital elements by Kenji Muraoka, are from 223 observations 1951 to 1999, including 9 Planets, Moon and 5 minor planets perturbations and non-gravitational effect of style II. The mean residual is +/- 0.91 arc seconds. Epoch = 1998 July 6.0 TT JDT = 2451000.5 T = 1998 July 12.59473 +/- 0.00022 (m.e.)
