SOLAR SYSTEM

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: -In 1543, Nicolaus Copernicus detailed his radical theory of the Universe in which the Earth, along with the other planets, rotated around the Sun. His theory took more than a century to become widely accepted.

Detailed explanation-3: -Which did Kepler notice about planetary motion that caused him to propose Kepler’s first law of orbital motion? The distance to the sun varies.

Detailed explanation-4: -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. The second law helps to establish that when a planet is closer to the Sun, it travels faster.

Detailed explanation-5: -Kepler used simple mathematics to formulate three laws of planetary motion. Kepler’s First Law stated that planets move in elliptical paths around the Sun. He also discovered that planets move proportionally faster in their orbits when they are closer to the Sun; this became Kepler’s Second Law.
