'Mars-centered' originates from Modern English, specifically combining 'Mars' (the Roman god and name of the planet) and the adjective-forming element 'centered', where 'Mars' referred to the planet and 'centered' derived from 'center' meaning 'middle point'.

'center' entered English from Old French 'centre', which came from Latin 'centrum', itself from Greek 'kentron'; 'Mars' comes from Latin 'Mars' (the god and planet), and the compound 'Mars-centered' is a modern English formation combining these elements.

Initially components referred separately to the planet 'Mars' and the notion of a 'center'; over time the compound evolved to mean 'focused on or organized around Mars' as a descriptive adjective.
