  1. The highest point of the orbit ✔
  2. The lowest point of the orbit
  3. The point where it launched

Why: Because orbits are ovals, a satellite's height changes as it goes around. The highest point is the apogee and the lowest is the perigee. The gee part means Earth.

Huh, didn't know that: Memory trick: Apogee is Away, Perigee is Pulled close.

The dad joke
Why was the satellite so proud at apogee? It was at the top of its game.
