What is the largest solar system in the Milky Way?

2MASS J2126 is around 7000 Earth-sun distances or 1 trillion kilometers away from its parent star, giving it the widest orbit of any planet found around another star. At such an enormous distance it takes roughly 900,000 years to complete one orbit, meaning it has completed less than 50 orbits over its lifetime.
