#UnusualTRIVIA: In Jonathan Swift's book "Gulliver's Travels" have a look at chapter 3 of "A Voyage To Laputa". It reads : "They have likewise discovered two lesser stars, or satellites, which revolve about Mars, whereof the innermost is distant from the centre of the primary planet exactly 3 of his diameters, and the outermost 5". There is nothing unusual in that except Gulliver's Travels was published in 1726 and Mars' 2 moons were first discovered by US astronomer Asaph Hall in 1877!
