My story takes place on a planet in another solar system. I don't think the characters would refer to their sunrise and sunset by such a long name as Centauri setting/rising. It's bound to be a shortened reference by this time (planet settled a century ago). Technically the star is the sun in their solar system. I worry that when I refer to the sun setting in the first paragraph, the readers are going to be thrown off if I call it a sunset and it will be jarring later to find out the story isn't taking place on Earth. Censet would be even more confusing. I could use it, especially with the hyphen (Cen-set). Some sci-fi authors do use new words and let the readers figure them out. Do you think space colonizers would call it starset? "The star was setting"? "Centauri was setting" and call it sunset later?
