As far as what most of the inhabitants of my planet believe, no. We just have a primary sun. However, there are some of the galactic-intellectual inhabitants that are debunking the theory, and introducing the "Nemesis" hypothesis that there is a very dim dwarf star that is in orbit along with our sun. There is no observational evidence of such a dwarf star, however was hypothesized to explain extinctual events that had occurred in the extreme past years.
