How To Add Extra Planets To Celestia

We have been receiving questions about how to add extra planets (models) to Celestia. We listen to what our website visitors ask us, so here’s a detailed tutorial of how to add planets, comets, asteroids, etc., to Celestia. The following tutorial works for objects in our own Solar System. [The guide for adding objects to other star systems is similar and we will post it later at our visitors’ request.]

Note: For everything you do on the PC, you need to have administrator rights; it needs to be your own computer or you need to have permission from the computer owner to make changes to the PC. This guide is written for computers running Windows, but the process is almost the same for Apple computers.
