Explanation:
Johannes Kepler used simple mathematics to describe how planets move.
Kepler was an assistant to the most accurate
astronomical observer of the time,
Tycho Brahe. Kepler was able to use
Brahe's data to show that planets
move in ellipses around the Sun (Kepler's First Law), that planets move proportionally faster in their
orbits when they are nearer the Sun (Kepler's Second
Law), and that more distant planets take proportionally longer to
orbit the Sun (Kepler's Third
Law).
Kepler lived from 1571 to 1630, during the time of discovery of the telescope.
Kepler was one of the
few vocal supporters of
Galileo's discoveries and the
Copernican system of planets orbiting the
Sun
instead of the
Earth.
