A NIGHT VIEW ON SATURN.
Although the light received from the sun is comparatively feeble, the nights upon Saturn must be splendid. Eight satellites—Mimas, Enceladus, Tethys, Uione, Rhea, Titan, Hyperion, and Japetus—accompany the planet; Mimas, the nearest to its primary, rotating on its axis in 22½ hours, and revolving at a distance of only 120,800 miles, whilst Japetus, the most remote, occupies 79 days in its rotation, and revolves at a distance of 2,314,000 miles.
Another most important contribution to the magnificence of the nights upon Saturn is the triple ring with which, as a brilliant setting, the planet is encompassed. To an "observer at the equator, this ring, which has been estimated by Sir William Herschel as scarcely 100 miles in thickness, must have the appearance of a narrow band of light passing through the zenith 12,000 miles above his head.—Page 213.
