Kepler devised three laws to explain the motion of the planets in the universe. According to the first law, a planet revolves around the Sun in a path similar to an ellipse with the Sun fixed at one of its focus points.

Explanation:

The Law of Ellipses, the first of Kepler's three laws of planetary motion, states that the route of the planets around the sun has an elliptical shape, with the core of the sun placed at one focus.

Johannes Kepler introduced his three laws of planetary motion in the early 1600s. Kepler's theory to elucidate the reasons behind such motions is not accepted anymore. However, his laws are to this day thought an objective representation of the motion of the planets.
