Depending on the specific observational model utilized for mapping the galaxy's structure, the nebula is situated within either the Perseus Arm or the Sagittarius Arm. Confirmation of its membership in the Milky Way, rather than a distant island universe, places it firmly within this local galactic structure, about 8,500 light-years from Earth, situated within the galactic disk.
