Detailed explanation-1: -Knowing then that the orbits of the planets are elliptical, johannes Kepler formulated three laws of planetary motion, which accurately described the motion of comets as well. Kepler’s First Law: each planet’s orbit about the Sun is an ellipse.
Detailed explanation-2: -The elliptical orbits of planets were indicated by calculations of the orbit of Mars. From this, Kepler inferred that other bodies in the Solar System, including those farther away from the Sun, also have elliptical orbits.
Detailed explanation-3: -With Tycho Brahe’s observations, Kepler set out to determine if the paths of the planets could be described with a curve. By trial and error, he discovered that an ellipse with the Sun at one focus could accurately describe the orbit of a planet about the Sun.
Detailed explanation-4: -Kepler’s third law-sometimes referred to as the law of harmonies-compares the orbital period and radius of orbit of a planet to those of other planets.
