At the moment the orbit tag doesn't have a wiki, and is used for two different purposes: artworks where the PoV is from orbit (eg. post #4231770, post #3737100, post #4898271), and artworks which feature a visible orbit around something (post #4243520, post #1755826)
My suggestion would be to move the first ones under from orbit, but i'm not sure how to disambiguate the ones in the second category.
(As a side note, there is also orbital ring, whose wiki applies for a single post out of 20, and therefore should probably be disambiguated too)
