Description

This galaxy is a likely member of the M81/ NGC2403 group of galaxies. Its distance is estimated to 4.7 mly and its diameter to 8100 light years. At first glance, it would appear to be an irregular galaxy, but there is evidence for a non-axisymmetric form of gas distribution, with a suggestion of central bar plus large-scale spiral arms. The morphological classification of this galaxy is SAa, which matches an unbarred spiral galaxy (SA) with very tightly-wound spiral arms. The actual visual form of the galaxy is a pure disk with no spiral arms or bulge. The bright, very knotty enveloppe has several dust patches involved.
