Question

27 which scientist developed three laws of planetary motion to describe how planets moved in our solar system?
johannes kepler
albert einstein
tycho brahe
isaac newton

Explanation:

Johannes Kepler developed three laws of planetary motion. These laws describe the motion of planets in the solar system. Kepler's first law states that planets move in elliptical orbits with the Sun at one focus. The second law, the law of equal areas, means that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. The third law relates the orbital period of a planet to its average distance from the Sun. Albert Einstein is known for the theory of relativity. Tycho Brahe made extensive astronomical observations. Isaac Newton formulated the laws of motion and universal gravitation.

Johannes Kepler
