You can make your own planet here, but you can’t have my name for it: http://planetquest.jpl.nasa.gov/system/interactable/1/index.html
This is simply one incarnation of Itaumiped, my own imaginary planet. Any time I need an imaginary planet, I use this anagram for “I made it up” as its name. Itaumiped’s star’s name, “Almausoped,” comes from “Also made up.”
I try to be prepared. After all, one never knows when one might need an imaginary planet — or star.
