Option 3 : Johannes Kepler
The correct answer is Johannes Kepler.
- Johannes Kepler published his first two laws about planetary motion in 1609, having found them by analyzing the astronomical observations of Tycho Brahe.
- Kepler’s three laws of planetary motion can be stated as follows:
- All planets move about the Sun in elliptical orbits, having the Sun as one of the foci.
- A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.
- The squares of the sidereal periods (of revolution) of the planets are directly proportional to the cubes of their mean distances from the Sun.
- Galileo is the father of science and observational astronomy, expanded man's understanding of various phenomena of the universe.
- He is also known as the father of modern physics.
- Nicolaus Copernicus was a Renaissance-era mathematician, astronomer, and Catholic canon who formulated a model of the universe that placed the Sun rather than Earth at its center.
- Sir Isaac Newton was an English mathematician, physicist, astronomer, theologian, and author who is widely recognized as one of the most influential scientists of all time and as a key figure in the scientific revolution.
