    • 1837, James Utting, “Of a conjunction of the Sun, Moon, planets, and satellites”, in The Mechanics Magazine, volume 26, page 381:
      As an illustration, suppose the number of fixed stars, visible in our best telescopes, to amount to one hundred millions, exclusive of their attendant planets and satellites, and that the Almighty had created as great a number of systems as above stated, in every second of time, during a nonillion of years, they would still be very far short of occupying one nonillionth part of infinite space, admitting them all to be placed at the same distance from each other as the fixed stars!
