Explanation:

- Option 1: Johannes Kepler

- Correct Answer: Kepler formulated three laws of planetary motion.

- Kepler described how planets orbit the sun in ellipses, with these laws explaining the speed and motion of planetary orbits.

- Option 2: Isaac Newton

- Newton is known for the laws of motion and universal gravitation.

- He expanded on Kepler's work by explaining the gravitational force behind planetary motion.

- Option 3: Galileo Galilei

- Galileo is famous for his pioneering use of the telescope and his support for heliocentrism.

- He did not formulate laws of planetary motion.

- Option 4: Tycho Brahe

- Brahe was an observational astronomer who collected accurate data on planetary positions.

- His data helped Kepler in formulating the laws of planetary motion.
