... that the first fictional depiction of the moons of Mars predates their actual discovery by a century and a half? Source: Swift writes that the astronomy-loving Laputians had discovered 'two lesser stars, or satellites, which revolve about Mars', which raced around the planet in 10 hours and 21.5 hours respectively. Gulliver's Travels was written in 1726, over 150 years before the discovery of Mars's moons, Phobos and Deimos. (4th Rock from the Sun: The Story of Mars)
