2 1 AU = million km Example: Mercury = 57.9 million km (57.9 x 10 6 km) 1 AU = million km Example: Mercury = 57.9 million km (57.9 x 10 6 km) 57.9 x 10 6 km x 1 AU = million million x 10 6 km x 1 AU = 57.9 x 10 6 km x 1 AU = 57.9 AU million 10 6 Venus = x 10 6 km 57.9 x 10 6 km x 1 AU = 0.4 AU 2

Law of Equal Areas Kepler's three laws of planetary motion: The speed at which any planet moves through space is constantly changing. 1. Law of Ellipses: Planets orbit the sun in a path described as an ellipse. faster A planet moves closest to the sun, and furthest from the sun. slower NOT a perfect circle, nor An elliptical path is oval a line it is an shape straight somewhere in between. If an imaginary line were drawn from the center of the planet to the center of the sun, that line would sweep same out the area in equal periods of time: Jul 9 12:17 PM Jul 9 12:43 PM elliptical an orbit is.
