Witch contribution did kepler make to viewing the solar system? a: he proposed the earth-centered model of the solar system. b: he proposed that gravity kept the planets in their orbit. c: he showed that planets moved in elliptical orbits. d: he proposed the sun-centered model of the solar system.

C: He showed that planets moved in elliptical orbits.

Explanation:

Copernicus described the solar system model with Sun at its center and planets along with their moons revolving about the Sun in circular orbits. This model is known as heliocentric model and this shift from geocentric model is known as Copernican revolution. Kepler supported the heliocentric model but showed that the planets revolved in elliptical orbits with the Sun at one of its foci. He wrote laws describing the planetary motion.
