Before the Invention of Teleſcopes, it ſeemed to contradict Copernicus’s Opinion, to make the Sun one of the fix’d Stars. For the Stars of the firſt Magnitude being eſteem’d to be about three Minutes Diameter; and Copernicus (obſerving that tho’ the Earth changed its Place, they always kept the ſame diſtance from us) having ventur’d to ſay that the Magnus Orbis was but a Point in reſpect of the Sphere in which they were placed, it was a plain Conſequence that every one of them that appeared any thing bright, muſt be larger than the Path or Orbit of the Earth: which is very abſurd. This is the principal Argument that Tycho Brahe ſet up againſt Copernicus. But when the Teleſcopes took away thoſe Rays of the Stars which appear when we look upon them with our naked Eye, (which they do beſt when the Eye-glaſs is black’d with Smoke) they ſeemed juſt like little ſhining Points, and then that Difficulty vaniſhed, and the Stars may yet be ſo many Suns. Which is the more probable, becauſe their Light is certainly their own: for it’s impoſſible that ever the Sun ſhould ſend, or they reflect it at ſuch a vaſt Diſtance. This is the Opinion that commonly goes along with Copernicus’s Syſtem. [They are not all in the ſame Sphere.] And the Patrons of it do alſo with reaſon ſuppoſe, that all theſe Stars are not in the ſame Sphere, as well becauſe there’s no Argument for it, as that the Sun, which is one of them, cannot be brought to this Rule. But it’s more likely they are ſcatter’d and diſpers’d all over the immenſe Spaces of the Heaven, and are as far diſtant perhaps from one another, as the neareſt of them are from the Sun.
