Kepler's laws of planetary motion

Kepler’s Law states that the planets move around the sun in elliptical orbits with the sun at one focus. There are three different Kepler’s Laws of Orbits, Areas, and Periods.

 

Laws of Orbits: The Planets move around the sun in elliptical orbits with the sun at one focus.

The orbit of any planet is an ellipse around the Sun with Sun at one of the two foci of an ellipse. But according to Kepler, he said that it is true that planets revolve around the Sun, but not in a circular orbit but it revolves around an ellipse.

 

Laws of Areas: The line joining a planet to the Sun sweeps out equal areas in equal interval of time.

The line joining a planet to the Sun sweeps out equal areas in equal interval of time. The rate of change of area with time will be constant.

 

Laws of Periods: The square of the time period of the planet is directly proportional to the cube of the semi major axis of its orbit.

The square of the time period of the planet is directly proportional to the cube of the semi major axis of its orbit.
