Names for a futuristic princess?

I’m writing a novel in which one of the characters is a former princess from a planet that was destroyed, and I can’t decide on a name for her. I want something unique, but I don’t want anything that seems…inelegant? It needs to “feel” like a name for a princess, but I don’t want something that is so obscure that my readers wouldn’t be able to pronounce the name (because honestly, people complain about that sort of thing even if a google search would give them the answer in 2 seconds).

I really love the name [name_f]Xanthe[/name_f] or Xanthea/[name_f]Xanthia[/name_f], but I don’t know if that would be easy enough to pronounce (I pronounce it as zan-thee, or zan-thee-uh, respectively).

I also like the name [name_f]Vanna[/name_f], but it didn’t go well with the original surname I had given the character (originally, it had been [name_f]Xanthia[/name_f] Vadro, but then I decided I preferred [name_f]Xanthe[/name_f], and I didn’t like the sound of [name_f]Xanthe[/name_f] Vadro). I was considering [name_f]Xanthe[/name_f] Sorra, but I don’t like [name_f]Vanna[/name_f] Sorra, or [name_f]Vanna[/name_f] Vadro (alliteration seems cheesy in this case).

I don’t want to give her a name that is commonly heard (because I want to have SOME fun with naming her), and I definitely want something feminine (as opposed to gender neutral).

Help?

[name_f]Asteria[/name_f] ([name_f]May[/name_f] be a bit cheesy for a space princess haha)

I do like [name_f]Vanna[/name_f] as well.

Pyra is nice too, makes me think of fire. [name_m]Fire[/name_m] evokes power.

I think [name_f]Xanthe[/name_f]/[name_f]Xanthia[/name_f] are wonderful and their pronunciations are fairly intuitive I’d say. What about
