Johannes Kepler was a student of Tycho Brahe.

Johannes Kepler joined the wealthy astronomer Tycho Brahe as a student as assistant. After the death of Brahe, Kepler used his observations data and based on it formulated the three laws of planetary motion. Galileo described the heliocentric model with planets revolving about the Sun in circular orbits which was corrected by Kepler. He corrected that the orbits are elliptical.
