Enhance your astronomy science fair project with Kepler’s third law…

Kepler's third law is all about the timing of the planets' orbits. It states, "the ratio between the square of the time needed by a planet to make a revolution around the sun and the cube of its average distance from the sun is the same for all planets." This law can be expressed in the following formula:
(Period of planet)^2/(Average orbit radius)^3 = Same result for all planets.

You can use this formula to collect data for your entry into a science fair competition
