  • n. The thickness of the ring is considerably less than a hundred miles. Its plane is inclined 7° to the planet's equator and 28° 10’ to the earth's orbit. When Saturn appears in the hind legs of Leo or the water of Aquarius, we see the rings edgewise, and they pass out of sight, remaining invisible as long as the sun shines upon the side away from us, for the ring only shows by the reflected light of the sun. They are best seen when the planet is in Taurus and Scorpio. As soon as Saturn was examined with a telescope (by Galileo), it was seen to present an extraordinary appearance; but this was first recognized and proved to be a ring by Huygens in 1659. In 1674 J. D. Cassini saw the separation between rings A and B, which is hence called the Cassinian division. (It has also been erroneously called Ball's division.) The dusky ring was discovered in 1850 at Cambridge, Massachusetts, by G. P. Bond. The ring was first assumed to be solid. Laplace showed that, upon that assumption, it must be upheld by the attractions of the satellites. B. Peirce in 1851 demonstrated the ring to be fluid—that is, to consist of vast numbers of particles, or small bodies, free to move relatively to one another. This had been suggested by Roberval in the seventeenth century. See cut on preceding page.
