Morphology

heliocentric = centric (semi-transparent) = helio + centric

The structure 'helio-' + 'centric' transparently means 'sun-centered' for learners who know the combining form 'helio'; however, 'helio-' is a Greek combining form not familiar to all B1 learners, so the relation is not fully transparent.

Etymology

The word heliocentric comes from Greek parts helio- meaning 'sun' and -centric meaning 'center', the same helio- you see in helium. So heliocentric literally means 'sun-centered', which is why it describes a model where the sun is the center of the system.
