Profile

Orbital Elements The following improved orbital elements by Kenji Muraoka, are from 461 observations 1967 to 1998, including 9 Planets, Moon and 5 minor planets perturbations and non-gravitational effect of style II. The mean residual is +/- 0.90 arc seconds. Epoch = 2000 Jan. 17.0 TT JDT = 2451560.5 T = 2000 Jan. 2.61656 +/- 0.00023 (m.e.) TT Peri. = 178.91098 +/- 0.00012 Node = 68.96653 +/- 0.00007 (2000.0) Incl. = 10.54133 +/- 0.00001 q = 1.5000475 +/- 0.0000004 AU e = 0.5189535 +/- 0.0000001 a = 3.1183002 +/- 0.0000004 AU n = 0.17898935 +/- 0.00000003 P = 5.507 +/- 0.0000010 years A1 = +0.013 +/- 0.004 A2 = +0.00178 +/- 0.00002

Finding Charts

Magnitudes Graph m1 = 14.0 + 5 log d + 7.5 log r [ ,-270] ( - 1999 Apr. 7) m1 = 8.5 + 5 log d + 20.0 log r [-270, 120] (1999 Apr. 7 - 2000 May 1) m1 = 12.1 + 5 log d + 6.7 log r [ 120, ] (2000 May 1 - )

The orbital elements are calculated by Kenji Muraoka. The charts are made with StellaNavigator Ver.2.0 for Windows (AstroArts / ASCII). The magnitudes graphs are made with Comet for Windows.
