In addition to this actual “night-light” or, to better understand this circumstance, “night-day,” comes a third light, which is the light of the fixed stars, which, when observed from Saturn, appears to be ten times stronger because of the planet’s pure and far-reaching atmosphere, and hence the stars also give off a light many times stronger than that which Venus, the evening star, does to earth in its brightest light. – Saturn, Chapter 2, Paragraph 7
