The early 17th century was a tumultuous time for scientists in Europe. Explore the process that Johannes Kepler undertook when he formulated his three laws of planetary motion. Kepler’s laws were crucial in the understanding of our solar system dynamics.

This video presents the story of Johannes Kepler and Tycho Brahe, who worked together at the turn of the seventeenth century. Animations show the geocentric model of the solar system (in which Earth was believed to be the center) and the heliocentric model (in which the Sun is the center).

This video contains nice illustrations and cartoons of both Kepler and Brahe and takes a fun look at how Kepler’s 3 laws of planetary motion were formulated in a historical context.
