'apogaic' originates from Greek, specifically the word 'apogaion', where 'apo-' meant 'away' and 'gē' (or 'gaia') meant 'earth'.

'apogaic' developed via Latin and French mediations from Greek 'apogaion' to Late Latin/French forms (e.g. French 'apogée') and then into English as 'apogee' and related adjectival forms such as 'apogaic'/'apogean'.

Initially it denoted the concept 'away from the Earth' (the point farthest from Earth in an orbit); over time it became specialized to mean 'relating to the apogee' in astronomical usage.
