WebMar 7, 2011 · The Ptolemaic worldview was superseded by Kepler's laws of planetary motion (ca. 1605). By Kepler's first law, planets move in elliptical orbits around the Sun at one focus. Kepler's second law implies that the planet sweeps out equal areas during equal intervals of time. This is a consequence of the conservation of angular momentum. WebAn ellipse is defined as the locus of all points such that the sum of the distances from two foci to any point on the ellipse is a constant.
