Not sure, I know M78 was the first reference to their home. 'Ultra Star' and 'Ultra Planet' are interchangable in Japanese from what I understand, but I think that's less the actual name of the Planet and more a description along the lines of 'the Ultras' world/home/planet'.

If I had to guess, I would suspect either in Jack's series Ace's or Taro's. Thought I suspect it's more towards the latter two.
