M-63 (NGC-5055)

M-63 is a large, bright type SAbc spiral galaxy located in the constellation Canes Venatici (The Hunting Dogs). It lies approximately 30 million light years from Earth and is 98,000 light years in diameter. It is inclined approximately 30 degrees from edge-on. It was discovered by Pierre Mechain in 1779 and was promptly added to Messier's catalog as number 63. It derives its common name "The Sunflower Galaxy because its spiral arms, rather than being continuous, are broken into numerous clumps. Because of this M-63 is called a "flocculent" galaxy.
