For Some reason whenever I try to use my star, it comes out as a brown dwarf, anyone know what I'm doing wrong?
It's because you have a brown dwarf as a second star in your system.
This star orbits around the main star as the center.
This does not work properly with newer versions of Space Engine.
If you have two or more stars in the system, you must create a 'StarBarycenter' for these stars.
I changed your scripts accordingly.
Two of the pictures are from SE 0.971. In SE 0.980 it will look different.
