This is a basic tutorial for building a 2-dimensional planetary system in excel. It has 2 bodies but it can be extended to more than that.
First part is theoretical but the second part of the video contains a cook book style implementation.
The model has a zoom button and a trail size button which can be used during the run. The universal attraction constant can also be changed on-the-fly. Of course once you build the model you can input your own custom planetary parameters. Send me a private message if you need a copy.
Congratulations for these skiils and thanks for sharing!
