There seems little agreement on its size and distance. I've seen reports of 10,400 light-years to 8,500 light-years for its distance and 200 light-years to 50 light-years for its diameter. It appears the latter differences are due to how the edge of it is measured. Just the star ball would give the smaller diameter, including further stars would lead to a larger diameter. Since this one is located against the stars of the Milky Way, how you define its "edge" is extremely difficult. Still, the wide disagreement surprised me.
