Kepler 9

Introduction

This simulation shows the system of exoplanets orbiting the star Kepler 9.

How it was created

It was created by making a new simulation, editing the name, color, radius, luminosity, and mass of the star to have the characteristics of Kepler 9, and then using the Edit / Add Object... command to add the three planets one at a time. The data for Kepler 9 and its three planets were taken from the following website:

This simulation was prepared on 14th September 2010.

What you can do with it

If you set the system running, you can watch how it evolves, and see how the orbital elements of the three planets slowly change with the passage of time. You can speed up the simulation by using the Evolve / Settings... command to increase the time step.
