Naming Places in SciFi & Fantasy
In Star Wars, the capital of the GALACTIC REPUBLIC / GALACTIC EMPIRE is Coruscant. I found the term CORUSCANT in an old 1828 English dictionary, with the following entry:
CORU'SCANT. a. [corusco, Latin]; Glittering by flashes; flashing.
Which makes sense as a name for a city-planet that never sleeps and you would be able to see the endless flashes of light moving along the dark side from heavy traffic in the skies.
This line of thought brings to mind two possible naming methods for places in science fiction:
Randomly flipping through a dictionary until you find a 'catchy' word; then figuring out what the planet would have to be like to get that name.
Same pattern as above, but using random Latin or Latin-derived words instead. This has the added cachet of being 'unusual', since you don't run across direct Latin words in English easily unless you're in certain professions.
