M63 is part a small grouping of galaxies which includes the grand design spiral M51. Unlike "Grand Design" spirals such as M51, M100, and M81, which all possess two symmetric large spiral arms, M63 is lacking in well defined spiral structure. Its fragmented and patchy spiral arms places it in the class of "flocculent" spiral galaxies which includes about one third of all spiral galaxies. Other well known galaxies of this type include NGC 2403, NGC 2841, NGC 3521, and M33. At present the best explanation for spiral arm formation is density wave theory (Lin and Shu 1964). This theory explains that density waves move through the disk at a different velocity than disk matter and stars. Stars move in and out of the density waves as they orbit the galaxy. As interstellar matter and gas encounters a density wave the matter tends to clump together. Giant molecular clouds form which then collapse, triggering star formation.
