The correct answer is True
Explanation:
Johannes Kepler was an important astronomer that lived from 1571 to 1630. He was mainly recognized for proposing a set of laws to describe the way planets move, and the general model of our solar system. In this model, the planets orbit around the sun, the orbitals of planets are elliptical and the sun is not in the center of the orbit. This model disproved other models that proposed orbits were circles, and due to its accuracy it was widely accepted; indeed this is still used nowadays and has been proven through observations, calculations, and experiments. Thus, it is true Kepler proposed the modern model of the solar system.
