Final answer:
Johannes Kepler drew up the Laws of Planetary Motion which describe the behavior of planets in their orbits.
Step-by-step explanation:
Johannes Kepler drew up the Laws of Planetary Motion. These laws describe the behavior of planets in their orbits. Kepler's three laws state: (1) planetary orbits are ellipses with the Sun at one focus; (2) in equal intervals, a planet's orbit sweeps out equal areas; and (3) the relationship between the orbital period (P) and the semimajor axis (a) of an orbit is given by P2 = a³ (when a is in units of AU and P is in units of Earth years).
