# 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)_

@s_gruppetta That's very cool. Thanks for posting this!

@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 this is really awesome! Given that it's for learning the coding side, I won't mark you down for using explicit integration 😜.

It's amazing how dynamic visualization can really solidify complex topics. Even when I've done iterative static computation in the past, dynamically-updating matplotlib plots really helped give me more intuition about the problem I was trying to solve.

@mattkram Yes, I find that I need to focus either on the coding aspect or on the science aspect, but you can't really do both–the article is already long as it is!

Agreed, in _real-world_ cases, the dynamic aspect adds an extra dimension which can help convey the results, in some cases, of course!

The 3D version uses #matplotlib for the animation
