Morphology

point + of + apoapsis

The phrase is fully compositional: 'apoapsis' already names the farthest point in an orbit and the 'point of' construction simply picks out that specific position. This follows a regular noun + of + noun pattern found across languages, so a B1 learner who knows the constituent meanings would understand it.

Etymology

The term point of apoapsis comes from a simple image: it is the point in an object's orbit that is farthest from the body it is orbiting. The part apo means 'away' and apsis means 'point', so the name really says 'the farthest point', which explains why it means that spot in the orbit.
