Celestia Files of the recent Dwarf Planet finds

In quick succession the team of Scott Sheppard and Chad Trujillo at the Cerro Tololo Inter-American Observatory have announced 3 new Dwarf planets. 2012 VP113 has an enormous 4000 year long orbit, and represent an object from the inner edge. The two others 2013 FY27 and 2013 FZ27 are more “traditional” Scattered disk objects (that seems ironic now).

Once again I have made a Celestia file, three files actually. In the clestia download I use, Sedna was ilsted as an Asterid, bot a dwarf planet, so if its orbot doesn’t turn up when you enable Dwarf Planets in Render | View Otions, but does when you turn on Asteroids, go to the data folder, find outersys.ssc (save a cpopy just in case), open and scroll down to Sedna and replace Class “asteroid” with Class “dwarfplanet”.  

As usual, copy the data here to a plain text file ( 2012VP113.ssc etc.) and copy the file to the Celestia extras folder.
