Question
Kepler.
Sun-centered, with the planets moving in perfect circles around the Sun.
The person who first showed that planetary orbits are ellipses was Copernicus. Newton. Galileo.Kepler.
The Copernican system for planetary motions is Earth-centered, with the planets, the Sun, and the stars mounted on crystal spheres, pivoted to allow the correct motions around Earth. Earth-centered, with the planets moving in epicycles around Earth. Sun-centered, with the planets moving in elliptical orbits and the Sun at one focus of the ellipse.Sun-centered, with the planets moving in perfect circles around the Sun.
Kepler's third law can be described in which of the following ways? The time to complete one revolution of its orbit depends on the size or radius of the planet. The smaller the radius of a planet, the more rapidly it rotates on its axis. The smaller the orbit of a planet, the longer the planet takes to complete one revolution. The larger the orbit of a planet, the longer the planet takes to complete one revolution.Explanation / Answer
The smaller the radius of a planet, the more rapidly it rotates on its axis.
