The Sombrero Galaxy (also Messier 104 and NGC 4594) is a peculiar galaxy of unclear classification in the constellation borders of Virgo and Corvus, being about 31.1 million light-years from the Milky Way galaxy. It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. It has a diameter of approximately 49,000 light-years, three-tenths the size of the Milky Way.
M104 has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its outer disk, which is viewed almost edge-on. The dark dust lane and the bulge give it the appearance of a sombrero hat.
The galaxy has an apparent magnitude of +8.0.
