But Galileo did not have Subsequent observations, which included spectroscopic studies by the late 19th century, confirmed that they are composed of smaller rings, each one made up of tiny particles orbiting Saturn. The ring system has four main components: a thick inner torus of particles known as the halo ring; a relatively bright, but extremely thin main ring; and two wide, thick, and faint outer gossamer rings.
