Ooh, glad you made this. Thanks!!

you're posting random stuff in a very short amount of time to reach the number of posts needed to make a thread or linking material, I guess. that's frown upon, per Forum Rules

Shoot, sorry... I didn't know that I couldn't post yet, I just really wanted to say thanks and stuff. But ok, I'll stop posting randomly. Sorry..

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.

54 Piscium with a brown dwarf as companion.

So far not so in SpaceEngine

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.

New to Space Engine and scripting. I have read the tutorials about how to create new objects and followed the instructions in the tutorial to the letter. However the star "Mono" does not appear in the F3 option in game. I am obviously do something wrong can anyone help a newbee ?
