UGC 4966, PGC 26512, LEDA 26512, MCG+09-16-005

With a diameter of about 150 000 light-years, NGC 2841 is larger than our own Milky Way galaxy. NGC 2841lies about 46 million light-years away and the disk of the galaxy shows no evidence for grand design structure (Leroy et al. 2008), although near-infrared observations do show some long dark spiral features in its interior (Block et al. 1996). NGC 2841 is an early-type Sc spiral galaxy (Bagetakos et al., 2011) and It is notable for being the archetype for the flocculent class of spiral galaxies.
