Morphology

planet + wheel

The compound is a straightforward, metaphorical composition: 'planet' (an orbiting body) + 'wheel' (a rotating object) yields a wheel that orbits a central element. This mapping is cross-linguistically common in technical vocabulary (e.g. 'planetary gear') so a B1 learner who knows both words can reasonably infer the intended meaning.

Etymology

Planet wheel gets its name from a simple picture: a small gear (the planet) turns and moves around a central 'sun' gear, just like planets orbit a sun. So, the term means a wheel or gear that revolves around the center of the gear system.
