I'm gonna try some Star Wars names, (if they aren't all taken by the time I start playing), and some names in the Elvish language from Lord of the Rings. Also some names from C.S. Lewis' Space Trilogy. He has some good names for planets and aliens in there.

I know already what I want to call my first planet. Wanna name it after my Crested Gecko, Jya'asam. But my main naming system, probably gonna be like mostly how we do it here on Earth. Like all planets in our solar system are named after greece gods. So I might gonna name planets and "solarsystem" after mythology gods/creatures/ojebects. Example; Thor, Anubis or Komaniu. With animals and plants, I am gonna do it either with pure latin. Or a mix between latin and old greece, as that are used in prehistorich creatures and plants. Example; Paulocretura or Microdakodon. With ships and other things, I don't really have any system for that. Might gonna find one when getting NMS in 11 days.
