apogee: [17] In its original, literal sense, a planet’s or satellite’s apogee is the point in its orbit at which it is furthest away from the Earth; and this is reflected in the word’s ultimate source, Greek apógaios or apógeios ‘far from the Earth’, formed from the prefix apo- ‘a(chǎn)way’ and gē ‘earth’ (source of English geography, geology, and geometry).
From this was derived a noun, apógaion, which passed into English via Latin apogeum or French apogée. The metaphorical sense ‘culmination’ developed in the later 17th century. The opposite of apogee, perigee [16], contains the Greek prefix peri- ‘a(chǎn)round’, in the sense ‘close around’, and entered English at about the same time as apogee. => geography, perigee
