The question is asking for the term used to describe the minimum distance from the Sun in a planet`s orbit. The correct answer is option 1: Perihelion.
Option 1: Perihelion refers to the point in a planet`s orbit where it is closest to the Sun. This is the opposite of option 2: Aphelion, which refers to the point in the orbit where the planet is farthest from the Sun. Options 3 and 4, Apogee and Perigee, are terms used in the context of Earth`s orbit around the Moon, and refer to the farthest and nearest points in that orbit, respectively.
Therefore, the correct answer is option 1: Perihelion.
