Orbital Elements The following improved orbital elements by Kenji Muraoka, are from 321 observations 1998 Oct. 2 to 1999 Dec. 27, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.75 arc seconds. Epoch = 1999 July 1.0 TT JDT = 2451360.5 T = 1999 June 25.25150 +/- 0.00006 (m.e.) TT Peri. = 226.35289 +/- 0.00013 Node = 153.35713 +/- 0.00014 (2000.0) Incl. = 170.15984 +/- 0.00002 q = 1.4677240 +/- 0.0000004 AU e = 0.9991009 +/- 0.0000021 1/a = +0.0006126 +/- 0.0000014 1/AU orig. 1/a = +0.000558 fut. 1/a = +0.001457
