What is the term for the point in an object's orbit when it is farthest from the sun?

• A. Perigee
• B. Aphelion
• C. Apogee
• D. Apoapsis

Answer: (C)

The term that describes the point in an object's orbit when it is farthest from the sun is known as aphelion. This term specifically applies to objects that orbit the sun, such as planets, asteroids, and comets. At aphelion, the gravitational pull from the sun on the object is at its weakest because of the increased distance, which significantly affects the object's orbital speed and other dynamic properties.

Perigee refers to the point in an orbit where an object is closest to Earth, while apogee indicates the point in an orbit around Earth when the object is farthest from it. Apoapsis is a more general term that refers to the farthest point in an orbit relative to the central body, but it does not specify the body. Since the question is specifically about an object's distance from the sun, aphelion is the most precise choice.
