Apparently Planet is dubious, but there's a bit of evidence for it.

Universal relies on certain translations and statements saying certain realms were universes like ib Majora's case with Termina and then the Sacred Realm and Lorule getting all flubbed up by the Triforce in some way.

Solar System is based on a realm having enough room for the Sun and a planet in it.

All very iffy due to being vague and sometimes having conflicting translations and other statements claiming something else.

So pretty much it's kinda all over the place, but the single best direct feats are multi-continent to planet level.
