About this app

This simulation will allow you to study Kepler’s laws. You will be given a holoprojector with which to observe the sun and one of its planets. The objective is to test Kepler’s laws and identify the unknown planet. To do so, you will need to find the area covered per unit of time and the semi-major axis.
