I love planatary, space, star, constellation, unusual and old english names
Here are a few names I've been playing around with:
Truely, Townsen, Jupiter, Tipler, Europa, Io (pronounced EYE-OH), Sweep, Pallene, Ophelia, Apoline, Ashalyn, Sinope, Thrym, Oberon, Lichen, Aldersky, Cephius, Ganymede, Callisto, Orion etc.
I find interesting names within my interests. I like googling star names and constellations. For instance, if you like classical music try google searching for names of violin/trumpet/whatever instrument makers names...
Google is my best friend.
