A really “cool” star

The Hubble site has a fascinating article on a newly discovered “L class” dwarf star. It’s about as small as a star can get and still have nuclear fusion, about 8 percent of the mass of our Sun.
Even more interesting is the fact that it has a “brown dwarf” companion in a tight orbit around it.
I almost wish that we had such a body in the outer solar system as a companion to the sun. Then again, such a body might perturb the Oort cloud and send many comets on paths into the inner solar system.
