Morphology

heliocentrism = heliocentric (transparent) = helio + centr + ism

Formed by adding the noun-forming suffix '-ism' to 'heliocentric' (sun-centered), so the doctrine/idea sense is directly derived.

Etymology

The word heliocentrism comes from Greek parts helio- meaning 'Sun', centr- meaning 'center', and -ism meaning 'belief' or 'theory'. So heliocentrism is the 'Sun-centered' idea that the planets move around the Sun.
