# Using Python to create a solar system
If anyone is looking for a fun exercise to flex their #Python #coding fingers…
Using just gravitational attraction between bodies, you can create your own 2D solar system with as many stars and planets as you want. Here's a binary star system with some relatively stable planets
Here's the article, including a detailed step-by-step tutorial, if you want to read more: **[Simulating Orbiting Planets in a Solar System Using Python](https://thepythoncodingbook.com/2021/09/29/simulating-orbiting-planets-in-a-solar-system-using-python-orbiting-planets-series-1/)**

…and there's also a 3D version _(next post)_
# 3D Solar System Using Matplotlib
The 3D version uses #matplotlib for the animation
Here's the article: **[Simulating a 3D Solar System In Python Using Matplotlib](https://thepythoncodingbook.com/2021/12/11/simulating-3d-solar-system-python-matplotlib/)**
@martinpeck both projects were fun to write (both the code itself and the articles!)
@martinpeck `turtle` is a fun module to use, beyond the basic _draw a few squares_ type of tutorials you find.
I use it a lot for teaching and I try to push it to its limits and use it to teach more advanced topics, too
@s_gruppetta I hadn't really thought about using turtle for this sot of thing. It makes perfect sense now I see it!
