Question

Quizplus · Accepted Answer

The Kepler model of the solar system is based on the idea that the Sun is at the center of the solar system and the planets move around it in elliptical orbits. This is different from the earlier Earth-centered models that had the planets moving in circular orbits or in epicycles around the Earth. Therefore, the best choice is D, which describes the Sun-centered, elliptical orbits of the planets.
