An alternate form of apogaeic; relating to the apogee or the farthest point in orbit.
Variant spelling of apogaeic, from apogee + -ic, where the vowels contracted differently in usage. Both forms have been used in astronomical terminology.
Apogaic and apogaeic are both correct, but they show how scientific language evolves—sometimes the long form wins, sometimes we shorten it, and in astronomy both survived because scientists weren't strict enough to enforce one rule.
