In case anyone else is interested, I created a text file containing the list of minor planet names found on this page:
http://www.cfa.harvard.edu/iau/lists/MPLists.htmlSome of them are just as difficult to pronounce as the generated ones, but many of them are notable and interesting. Plus, I think it's cool having the in-game planets named after actual (minor) planets. There's over 15,000 names in the list, so you shouldn't notice too much repetition
Even if you're not interested in the entire list, it might serve as filler for your own list.
I also want to put together a list of actual planets, but many of these minor planets have really interesting names and I thought they fit well.
