軌道要素The following improved orbital elements by Kenji Muraoka, are from 141 observations 1977 to 2000, including 9 Planets, Moon and 5 minor planets perturbations and non-gravitational effect of style II. The mean residual is +/- 0.75 arc seconds. Epoch = 1999 Dec. 8.0 TT JDT = 2451520.5 T = 1999 Dec. 16.22615 +/- 0.00046 (m.e.) TT Peri. = 355.85857 +/- 0.00031 Node = 50.58924 +/- 0.00005 (2000.0) Incl. = 20.13872 +/- 0.00002 q = 1.5497182 +/- 0.0000023 AU e = 0.5879217 +/- 0.0000006 a = 3.7607372 +/- 0.0000020 AU n = 0.13514333 +/- 0.00000011 P = 7.293 +/- 0.0000059 years A1 = +0.096 +/- 0.022 A2 = +0.00716 +/- 0.00038
