Define Kepler ' law. Full explanation with example.
Answers
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.
Explanation:1: a statement in astronomy: the orbit of each planet is an ellipse that has the sun at one focus
2: a statement in astronomy: the radius vector from the sun to each planet generates equal orbital areas in equal times
3: a statement in astronomy: the ratio of the square of the revolution period to the cube of the orbital major axis is the same for all the planets
Kepler's law is based on space science
