Question

what is true about the foci of a planet in elliptical orbit? (1 point)
the sun is located at one focus.
earth is located in the center of the orbit.
the sun is located in the center of the orbit.
earth is located at one focus.

Explanation:

Kepler's first law of planetary motion states that planets move in elliptical orbits with the Sun at one of the foci. Earth is a planet, so it orbits the Sun. The center of an elliptical orbit is not a focus. The Sun is the central body around which planets (including Earth) orbit, and it is at one focus of the elliptical orbit, not the center. Earth is not at the center or at a focus (except in a heliocentric - view where the Sun is at a focus).

Answer:

The sun is located at one focus.
