where is the sun located on earth’s elliptical orbit? (1 point)
○ at the center of the two foci
○ at a focus
○ at the aphelium
○ at the perihelium

Explanation:

To determine where the sun is located on Earth's elliptical orbit, we use the concept of ellipses in orbital mechanics. An ellipse has two foci, and in the case of Earth's orbit around the Sun, the Sun is positioned at one of these foci. The "center of the two foci" is incorrect as there's no such central point for the foci. Aphelium is the point in Earth's orbit farthest from the Sun, and perihelion is the closest point, so neither of these is where the Sun is located.

Answer:

B. at a focus
