Part of the M81 group,[4] NGC 2976, located 1° 20′ southwest of M81, is an unbarred spiral galaxy. The inner structure contains many dark lanes and stellar condensations in its disk. The galaxy is sometimes classified as Sdp because its spiral arms are difficult to be traced. The bright inner part of this disk appears to have a defined edge. These distortions are results from the gravitational interactions with its neighbors.
NGC 2976 was discovered by William Herschel on November 8, 1801, and cataloged as H I.285.
