Question

Name the scientist who gave the three laws of planetary motion.

Answer 1

Hint: We know that all the planets revolve around the sun in fixed orbits. The three laws of planetary motion define the motion of the planets in the solar system around the sun. These laws modified the theories like the heliocentric theory of Nicolaus Copernicus, replacing the circular orbits and epicycles with elliptical trajectories.

Complete answer:
We know that, there are many laws published in the old times and among these there are three laws of planetary motion which are given by Johannes Kepler.
So, Johannes Kepler is the name of the scientist who gave the three laws of planetary motion. He got his observations in the 16th century and then published the laws afterwards. Firstly, he published two laws in the year 1609 and then after 10 years he published the third law of planetary motion.
The three laws of planetary motion include the position and the revolution of the planets and their orbits around the sun.
We also know that these laws helped Sir Isaac Newton when he formulated his law of gravitation between the Earth and the Moon and between the Sun and the other planets. Also, Kelper’s law was very useful to the motions of natural and artificial satellites.

Hence, the correct answer is Johannes Kepler.

Note: According to history we know that there are many laws published in the old time and among these there are three laws of planetary motion which are given by Johannes Kepler. These laws helped many scientific experiments and the laws which were published by different scientists after that.
