perihelion
The area of an orbit closest to the Sun, and that moves fastest, is called the "perihelion."
The area of an orbit closest to the Sun, and moves fastest, is called the perihelion.
To determine or verify this answer, you can refer to basic principles of celestial mechanics. Every planet or celestial body in our solar system moves in an elliptical or oval-shaped orbit around the Sun. This orbit is characterized by two key points called the perihelion and aphelion.
The perihelion refers to the point in an orbit where the object is closest to the Sun. At this point, the object experiences the strongest gravitational pull from the Sun, resulting in increased acceleration and higher orbital velocity. As a result, the object moves at its fastest speed during this part of the orbit.
Conversely, the aphelion is the point farthest from the Sun in an orbit. At this point, the object experiences weaker gravitational pull, resulting in lower acceleration and slower orbital velocity.
Therefore, the perihelion is the term used to describe the area of an orbit closest to the Sun, where the celestial body moves the fastest.
