Morphology

solar + system

The meaning is directly derivable from 'solar' (pertaining to the Sun) + 'system' (a collection of related parts), so 'solar system' straightforwardly denotes the Sun and its associated bodies. This adjectival+noun composition is a standard, transparent pattern found across many languages, so a B1 learner who knows both constituents will readily understand the term.

Etymology

The noun solar system comes from a simple picture: the Sun at the center with the planets and other objects moving around it like parts of one 'system', so the phrase means the Sun plus everything that travels around it.
