Orbital Elements The following improved orbital elements by Kenji Muraoka, are from 157 observations 1998 Apr. 2 to June 17, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.62 arc seconds. Epoch = 1998 Nov. 3.0 TT JDT = 2451120.5 T = 1998 Nov. 16.62892 +/- 0.00721 (m.e.) TT Peri. = 236.32244 +/- 0.00377 Node = 341.38353 +/- 0.00434 (2000.0) Incl. = 109.71363 +/- 0.00142 q = 2.1333872 +/- 0.0008238 AU e = 0.8235055 +/- 0.0000442 a = 12.0875561 +/- 0.0035549 AU n = 0.02345289 +/- 0.00001035 P = 42.025 +/- 0.0185392 years (+/- 6.77 days)
