Which term describes the point in a satellite's orbit where it is closest to the main body?

Explanation:
In an elliptical orbit, the distance to the body being orbited changes, with the closest point called perigee. For a satellite around Earth, perigee is the point where it is nearest to Earth, while apogee is the farthest point. Perihelion is the analogous term for the closest point to the Sun, and Slack Water and Spring Tide refer to tidal phenomena, not orbital geometry.
