In astronomy, Kepler's laws of planetary motion are three scientific laws describing themotion of planets around the Sun. Illustration of Kepler's three laws with twoplanetary orbits. The orbits are ellipses, with focal points ƒ1 and ƒ2 for the first planet and ƒ1 and ƒ3 for the second planet.

1.Every planets revolves in eleptical orbit in which sun lies in two of one point
2.every planet revolve around the sun in such a way that the line joining the planet to the sun sweeps over equal areas in equal interval pf time .
3.the speed is greeter when it is nearest the sun and less when the planet is farher around the sun
4.the cube of the mean distance of planet from the sun is directly propostinal to square of time it takes to move around sun .
THEY ARE LAWS OF KEPLER'S LAWS OF PLANETERY MOTION.
