The sky at night presents us a sight of wonders, which must raise the astonishment of every attentive observer of nature. But from whence comes it, that so few consider the firmament with attention? I am willing to believe, that in general it proceeds from ignorance; for it is impossible to be convinced of the greatness of the works of God, without feeling a rapture almost heavenly. O how I wish to make you share this divine pleasure! Raise your thoughts for this purpose towards the sky: It will be enough to name to you the immense bodies which are strewed in that space, to fill you with astonishment at the greatness of the artificer. It is in the center of our system that the throne of the sun is established. The body is more than a million of times larger than the earth. It is one hundred millions of miles distant from it, and notwithstanding this prodigious distance, it has a most sensible effect upon our sphere. Round the sun move twenty-one globular bodies, seven of which are called planets, the other fourteen, moons or satellites; they are opake, and receive from the sun light, heat, and perhaps also their interior motion. Georgium Sidus, Saturn, Jupiter, Mars, the Earth, Venus, and Mercury, are the names of the seven principal planets. Of these seven, Mercury is nearest the sun, and for that reason is mostly invisible to the astronomer. As he is near nineteen times smaller than our earth, he contributes but little to adorn the sky. Venus follows him, and is sometimes called the morning, and sometimes the evening star. It is one of the brightest of the heavenly bodies, whether it precedes the sun-rise, or succeeds the setting sun. It is near as large again as our earth, and is about sixty-eight millions of miles distant from the sun. After Venus comes our earth, round which the moon moves, as a secondary planet. Mars, which is the fourth planet, is seven times smaller than our globe; and its distance from the sun is one hundred and forty-four millions of miles. Jupiter, with his belt, is always distinguished by his splendor in the starry sky: it seems in size to surpass all the fixed stars; it is almost as bright as Venus in all her glory, except that the light of it is less brilliant than the morning star. How small our earth is in comparison with Jupiter! There would not be less than eight thousand globes like ours, necessary to form one equal in size to that of Jupiter. Saturn, whose distance from the sun is upwards of nine hundred millions of miles, was thought the remotest planet until the late discovery of the Georgium Sidus, whose distance is eighteen thousand millions of miles, and its magnitude eighty-nine times greater than our earth. In the mean time, the sun, with all the planets which accompany it, is a very small part of the immense fabric of the universe. Each star, which from hence appears to us no larger than a brilliant set in a ring, is in reality an immense body which equals the sun both in size and splendor.
