Question

DESCRIBE KEPLER LAW OF PLANETARY MOTION.

Answer 1

Answer:

Kepler’s laws of planetary motion, in astronomy and classical physics, laws describing the motions of the planets in the solar system. They were derived by the German astronomer Johannes Kepler, whose analysis of the observations of the 16th-century Danish astronomer Tycho Brahe enabled him to announce his first two laws in the year 1609 and a third law nearly a decade later, in 1618. Kepler himself never numbered these laws or specially distinguished them from his other discoveries.

Answer 2

Answer:

1. keplers first law :The orbit of a planet is an ellipse with the sun at one of the foci.
2. keplers second law :The line joining the planet and the sun sweeps equal areas in equal intervals of time.
3. keplers third law:The square of its period of revolution around the sun is directly proportional to the cube of the mean distance of a planet from the sun.
