SOLAR SYSTEM

Detailed explanation-1: -Kepler’s First Law: each planet’s orbit about the Sun is an ellipse. The Sun’s center is always located at one focus of the orbital ellipse. The Sun is at one focus. The planet follows the ellipse in its orbit, meaning that the planet to Sun distance is constantly changing as the planet goes around its orbit.

Detailed explanation-2: -Kepler’s first law means that planets move around the Sun in elliptical orbits. An ellipse is a shape that resembles a flattened circle. How much the circle is flattened is expressed by its eccentricity. The eccentricity is a number between 0 and 1.

Detailed explanation-3: -Kepler’s Law of Areas – The line joining a planet to the Sun sweeps out equal areas in equal interval of time. Kepler’s Law of Periods – The square of the time period of the planet is directly proportional to the cube of the semimajor axis of its orbit.

Detailed explanation-4: -“The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.” That’s Kepler’s Third Law in a nutshell, and it arises from the third physical property of ellipses, related to its various axis points.

Detailed explanation-5: -Kepler’s First law: Every planet revolves around the Sun in an elliptical orbit and Sun is situated at one of its two foci. It is also termed as ‘the Law of Orbits’.

Detailed explanation-6: -If the size of the orbit (a) is expressed in astronomical units (1 AU equals the average distance between the Earth and Sun) and the period (P) is measured in years, then Kepler’s Third Law says P2 = a3.
