Orbital Elements The following improved orbital elements, by Kenji Muraoka are from 368 observations 1994 Mar. 20 to 1996 Dec. 14, perturbations by 9 Planets, Moon and 5 minor planets were taken into account. The mean residual is +/- 0.71 arc seconds. Epoch = 1994 June 17.0 TT JDT = 2449520.5 T = 1994 June 29.63107 +/- 0.00009 (m.e.) TT Peri. = 192.12218 +/- 0.00003 Node = 51.12849 +/- 0.00004 (2000.0) Incl. = 135.96108 +/- 0.00002 q = 1.9477569 +/- 0.0000006 AU e = 0.9964285 +/- 0.0000018 1/a = +0.0018336 +/- 0.0000009 1/AU ( P = 12736 years ) orig. 1/a = +0.0021377 fut. 1/a = +0.0022850
