NGC 3585 has a bright central bulge and a disk that is less prominent than that of spiral galaxies. This galaxy was discovered by the astronomer William Herschel in 1784. NGC 3585 is notable for its relatively low star formation rate, which is characteristic of lenticular galaxies. Its structure and composition provide valuable insights into the evolution of galaxies in the universe.
