Astronomy Demonyms

One from America is an American. One from Peru is a Peruvian. What would one from Mars be called? Given an astronomical object, can you figure out its demonym?
Source: Wikipedia. (Yeah, I was also surprised by the existence of that page.)
keep in mind that adjectivals and demonyms are not always the same.

Lunar (moon) and Solar (sun) would suffice. Those extra letters don't do anything.

That's the difference between a demonym and an adjectival. Check the source page. You wouldn't call a person from the Sun "A Solar"; the correct name is "A Solarian".
