    Kepler (1571-1630) had studied for many years the records of observations on the planets made by TYCHO BRAHE ,and discovered three laws now known by his name.Kepler's law states 01.The planet describes ellipses about the sun as one focus 02.The line joining the sun and the planet sweeps out equal areas in equal times 03.The squares of the periods of revolution of the planets are proportional to the cubes of their mean distances from the sun.

    I law :-Law of elliptical orbits "The path of a planet is an elliptical orbit ,with sun at one of its foci". II Law:-Law of equal Areas "The radius vector,drawn from the sun to a planet sweeps equal areas in equal interval of time" Or "The areal velocity(area swept out by planets per unit time) of a planet is constant". III Law:-Law of periods :(Harmonic law) "The square of the period of the revolution of a planet round the sun is proportional to the cube of the semi-major axis of the elliptical orbit ". Kepler's third law is consistent with the inverse square nature of the law of universal gravitation. According to Kepler's second law, when the planet is closest to the sun its speed is maximum and when it is farthest from the sun its speed it minimum. HOPE IT HELPS YOU ^_^
