Generalized to all planets, it states that the orbit of a planet follows an ellipse with the Sun at one focus. Do you know how to draw an ellipse? We show you a neat trick in this video using a piece of string, a pencil, and a couple of pushpins. ✵✵✵✵✵ CHAPTERS You can jump to chapters in the video here: 0:00 Introduction -Tycho Brahe data 0:41 Competing theories 1:33 The ellipse and elliptical orbits 2:15 Eccentricity 3:03 General statement of Kepler's 1st Law We have videos for all 3 laws!
