Orbital Elements Perturbed ephemeris below is based on elements from NK 573. Epoch = 2454920.50000 TT T = 2454938.75931 TT Peri. = 156.80416 a = 3.9442172 AU Node = 238.06666 J2000.0 e = 0.5851811 Incl. = 16.86718 q = 1.6361359 AU

Magnitudes Graph m1 = 18.0 + 5 log d + 20.0 log r

The orbital elements are calculated using the Minor Planet & Comet Ephemeris Service. The magnitudes graphs are made with Comet for Windows.
