Hello Commanders! I was exploring rather close to Heart and Soul Nebula this afternoon when I happened upon a Red Super Giant. Upon looking into the galaxy map I was a surprised to see it was a Class M (M1 I) Red Supergiant and it had yet to be discovered! System HD 237006. Radius of 116.8. I was quite pleased with the find and wanted to share with all. I have discovered two other Red Supergiants both Class K (K0 IAB). I noted that EDSM and the system map classify these as one group (Red Super Giant) but the Codex and the Galaxy map separate them out. I was uncertain as to why this was and was wondering if anyone had any thoughts. Just thought I would share!
Red (M) Super Giant

Congrats on the find! This is a catalog star, so one that was hand placed because it actually exists in real life, which would be why it is an M class super giant as opposed to the K class red super giants which are procedurally generated.
Understood, however I was just wondering why lumped together in the system map descriptions but clearly considered separate entities. Agreed all red super giants I have encountered that are procedurally generated are K Class (IAB in the two other cases I have found). The only M Class red super giants appear to be in authored systems.
Which makes me ask what is the definition of "super"? Honest question as I'm not sure where the line is.
"Red supergiants are massive stars near the end of their lives" -- this one is supermassive, it is about 0,39 solar masses
Which is OK for a normal red dwarf. However red dwarves live way longer than 5,2 billions of years, so it shouldn't be near it's end. And with such a mass and such a radius the star should have lost it's atmosphere long ago. Big surprise from Stellar forge once again.
According to SIMBAD :
So it should really be K type. One of many anomolies in the in game versions of RL stars..
