A grand design spiral galaxy is a spiral galaxy with prominent and well-defined spiral arms, as opposed to multi-arm and flocculent spirals which have subtler structural features. The spiral arms of a grand design galaxy extend clearly around the galaxy, covering a significant portion of the galaxy's circumference. As of 2002, approximately 10 percent of all currently known spiral galaxies are classified as grand design type spirals,[1] including M51, M74, M81, M83, and M101.
