Question 1
Quick RecallState Kepler's law of orbits and explain how it differs from the Copernican model.
- Kepler's law of orbits states that all planets move in elliptical orbits with the Sun situated at one of the two foci of the ellipse.
- The Copernican model assumed that planets move in perfect circular orbits around the Sun, which is a special case of an ellipse.
- Kepler's law was a significant departure because it correctly described the observed non-uniform speeds of planets at different points in their orbits.
