Its exact nature is uncertain.[4][5] At first glance, it appears like a barred spiral galaxy seen face on. However, further examination has shown that what appears to be the bar is actually the main structure of an edge-on spiral galaxy, and the galaxy has structure like that of polar-ring galaxies.[3][6]
