NOTE: If viewing this file and it appears confused, make the window very wide! The numbers are all in the proper format for easy use in Starry Night's orbit editor. Just click on the word Sun in the planet floater and then click on add. In the first window that appears select the comet as the type of object you want to add. Please see the manual for more information. The orbital information should have the reference plane set at Ecliptic 2000 and the Style should be pericentric. Don't forget to use copy and paste to ease the input of the orbital data into Starry Night. This file kindly prepared by the IAU Minor Planet Center & Central Bureau for Astronomical Telegrams.
