Encyclopedic overview

NGC 2397 is a flocculent spiral galaxy located in the southern Volans constellation, about one degree to the SSE of Delta Volantis. English astronomer John Herschel discovered the galaxy on February 21, 1835. It is located at a distance of approximately 69 million light years from the Sun, and is a member of the small NGC 2442 group that includes NGC 2434.

The morphological classification of NGC 2397 is SB(s)b, which indicates this is a barred spiral (SB) with no ring structure around the nucleus (s) and moderately tightly–wound spiral arms (b). The nucleus is partly obscured and consists of older yellow and red stars; more recent stars have formed within the outer blue spiral arms, which also feature protrusions of dust.
