The Description and Use of the Globes and the Orrery - To Which is Prefix'd, by Way of Introduction, a Brief

A Brief Account of the Solar System, and of the Fixed Stars. Of the Order and Periods of the Primary Planets revolving about the Sun; and of the Secondary Planets round their respective Primaries. The Sun is placed in the midst of an immense space, wherein six opaque spherical bodies revolve about him as their center. These wandering globes are called the Planets, who, at different distances, and [Pg 2] in different periods, perform their revolutions from West to East, in the following order: 1. Mercury is nearest to the Sun of all the planets, and performs its course in about three months. 2. Venus in about seven months and a half. 3. The Earth in a year. 4. Mars in about two years. 5. Jupiter in twelve. And lastly, Saturn, whose[1] Orbit includes all the rest, spends almost 30 years in one revolution round the Sun. The distances of the Planets from the Sun are nearly in the same proportion as they are represented in Plate 1. viz. Supposing the distance of the Earth from the Sun to be divided into 10 equal parts; that of Mercury will be about 4 of these parts; of Venus 7; of Mars 15; of Jupiter 52; and that of Saturn 95. ......Buy Now (To Read More)
