'heliocentric' originates from Greek, specifically the word 'hēlios,' meaning 'sun,' and 'kentrikos,' meaning 'pertaining to a center.'

'heliocentric' was derived from the Greek word 'hēliokentrikos' and eventually became the modern English word 'heliocentric.'

Initially, it meant 'pertaining to the sun as a center,' and this meaning has largely remained the same in modern usage.
