Morphology
The phrase is a straightforward ADJ+NOUN composition: 'orbital' (relating to an orbit) modifies 'rotation' (a turning/movement), so the combined meaning — rotation or movement occurring in an orbital path — is directly inferable from the parts. This compositional pattern is common across languages and does not require specialized idiomatic knowledge, so a B1 learner who knows both words can reasonably deduce the meaning.
Etymology
Orbital rotation comes from the simple image of a ball on a string swung around a post. The word orbit is the path around something and rotation is the turning motion, so the phrase means 'the motion of an object moving in a curved path around another body', like a planet going around a star.
