Isn’t “Alien Planet” redundant unless somebody knows that actual Aliens live there?

It's actually a contradiction in terms. If it is their planet, they are not aliens there. If they came here, they would be aliens.. If we went there, we would be the aliens. I learned this on "Lost in Space".

Not if you define alien as "other than".
