n, they rotate on their axes in the sametime as they revolve round their primary. This is inferredfrom the fact that their light varies, and that they are al-ways brightest and dullest in the same positions with re-gard to Jupiter and the Sun. 280. Saturn (£>).—Saturn, which is next to Jupiter indistance from the Sun, is also next to it in size, having avolume about 750 times that of the Earth. Its day isnot half so long as ours, but it is 29-J of our years in mak-ing one complete revolution in its orbit. 281. Saturn, whichis belted like Jupiter,is surrounded not onlyby eight moons, butby a series of rings,the innermost one ofwhich is transparent.The belts have beenalready referred to(Art. 277). Seven ofthe moons were known for sixty years before the eighthwas discovered. Their diameters, distances from theirprimary, etc., are given in Table III. of the Appendix.The equator of Saturn, unlike that of Jupiter, is greatlyinclined to the ecliptic; transits, eclipses, and occupations

Satukn and its Moons. with our Moon in size? How, in distance from the primary? In what respectdo they resemble our Moon ? From what is this inferred ? 280. What planetranks next to Jupiter in size ? How does Saturn compare with the Earth insize? How do Saturns day and year compare with ours? 281. How manymoons has Saturn ? By what else is it surrounded ? In what respect is Saturnveiy unlike Jupiter? In what plane do the orbits of Saturns satellites mostly THE BINGS OF SATUEN. 147 of the satellites, the orbits of which for the most part liein the plane of the planets equator and rings, happen butrarely. 282. It is to the rings that most of the interest of thisplanet attaches. We may imagine how sorely puzzled theearlier observers, with their very imperfect telescopes,were, by these strange appendages. The planet at firstwas supposed to resemble a vase; hence the name Answ,or handles, given to the rings in certain positions of theplanet. It was next supposed to consist of three bodies,
