Can someone update Thuban here? It has an M class binary when it's companion should be an A2 class binary.

Is this system here as it should be? If it is, I will make a planet mod for it.

 PSR J0337+1715
Scientists Test Einstein’s Theory of Gravity on Unique Triple-Star System  (It's already from 2018.)

This system is only a binary system in SpaceEngine. But it is actually a triple system.
I made a script for it.
