The
morphological classification of this galaxy is RSB0(r),[3] indicating a
barred lenticular galaxy (SB0) with outer (R) and inner (r) ring structures. It hosts two nested stellar bars; the rotation frequency of the secondary bar is higher than that of the primary one.[3] Double bars of this type are relatively common, having been found in ~30% of barred lenticulars. The inner bar appears to be counter-rotating relative to the outer bar,[8] with the two passing cleanly through each other.[9] The stellar mass of the galaxy is 1.7×1010M☉ while the halo mass is 6.6×1011M☉.[7]
