I want to know what kind of art style this is, like maybe a specific name for it? I'm referring to the sorta cartographic aspects, with the circles and lines around the planets and all that crap.
It isn't.
Not every visual design element constitutes a unique style.

It's just a cartographic inspired UI design, anon. One that would work a lot nicer on m+k if I might add, but still. It's very pretty and well organized. It falls less into a specific artstyle (as far as I can tell, the planets are taken from their concept art and maybe refined a little bit) but the look you're refering to is mostly adding cartographic elements to create a starchart in a very nicely designed space with solid typography.
