Who among the following is credited with postulating three laws of planetary motion?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Johannes Kepler.
- Johannes Kepler is credited for postulating the three laws of planetary motion. They describe how (1) planets move in elliptical orbits with the Sun as a focus, (2) a planet covers the same area of space in the same amount of time no matter where it is in its orbit, and (3) a planet’s orbital period is proportional to the size of its orbit (its semi-major axis).
- Together, these scientific principles help explain the movements of the planets around the sun in our solar system.
