The system "Nu Scorpi" seems incomplete. It should have 7 stars.
Nu Scorpii has seven stars in SpaceEngine!
You just have to get pretty close to the stars to see it.
I am interested in the concept of a star system with 8 or 9 stars. One of them being a B type (Subgiant), 3 being A type (1 A class star being subgiant), 2 G type (1 subgiant), 1 a white dwarf, 1 M type, and 1 K. With the G type being in a close binary (orbiting in 24 hours or less with the other G type being something like a G8V star). Though you can spin your own flair on this. Star systems like this are really interesting to me and would make a great solar system, but I'm unsure how to do barycenters and orbits involving binary objects. The goal of this system is that it is habitable. Would it even be possible with those types of stars? Feel free to make it habitable by having different stars.
B and A stars are generally not suitable for life-bearing star systems. These stars don't live long enough.
Giant stars, including sub-giants, are also unsuitable.
A G9 sub-giant might develop life, but it wouldn't get very old, so to speak.
