apogee \AP-uh-jee\ (noun) - 1 : The point in the orbit of the moon or

center of the earth. 2 : The farthest or highest point; culmination.
"He had suggested that perhaps a human life was a simple parabola in
which one never knew when the apogee -- the highest, most sublime
point -- had been." -- Dan Simmons, 'A Winter Haunting'
Apogee is derived from Greek apogaion, from apogaios, "situated (far)
away from the earth," from apo-, "away from" + gaia, "earth."
