Here's a breakdown:
* Apoapsis: The general term for the point in an orbit furthest from the central body (could be a planet, star, or other celestial object).
* Specific terms: For orbits around specific objects, we use more specific terms:
* Apogee: Furthest point from Earth in an orbit.
* Aphelion: Furthest point from the Sun in an orbit.
* Apogalacticon: Furthest point from the center of the Milky Way galaxy in an orbit.
