I think I read somewhere we nearly were a binary star system with jupiter as the second star, if not for the rest of the gasses formed saturn which also made sure that jupiter moved out.
I remember briefly hearing that speculation but then PBS Spacetime putting that theory to bed by explaining that (IIRC) Jupiter would have to be much more massive for it to have had a chance at becoming a brown star.
