Question

The three laws of planetary motion were given by

• A. Aristotle
• B. Kepler
• C. Copernicus
• D. Tycho Brahe

Answer 1

The correct option is B Kepler

The three laws of planetary motion are given by $Kepler$ and are often called as Kepler's law of planetary motion.

These three laws are-

1. The orbit of a planet is an ellipse with the Sun at one of the two foci.
2. A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.
3. The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its orbit.

Hence correct answer is option $B$
