Okay I have some free time so I will try to help. ^^
I personally love names of towns if they are in different languages. For instance my town is called Keiros, a play on the word for pathway in Japanese. So here are some names that are in Latin for some words that you might like?
Galaxia, the Latin word for galaxy. It's certainly simple.
Pelagius, derived from the Latin word of sea used as an adjective.
Stellarum based on the word for stars in Latin.
Kessho, based on the Japanese word for crystal.
Suta, based on the Japanese word for star.
Monokuro, based on the Japanese word for monochrome.
I hope some of these helped. I didn't really think of them they are just what came up when I typed the words into Google Translate. Let me know what you think.
