Investigate other planet planet implementations #6
Description
The current planetplanet code hasn't been updated since 2007 and is python 2 only. It's a miracle it even works today.
On the other hand, it seems to still be in use by many planets on the internet :/. For ex: https://planetpython.org/ and many others linked on that site.
Add suggestions in the comments below, pros and cons if you know them.
