150 years before the were predicted in
Gullivers Travels
  • They have likewise discovered two lesser Stars,
    or Satellites, which revolve about Mars whereof
    the innermost is distant from the Center of the
    primary Planet exactly three of his Diameters,
    and the outermost five the former revolves in
    the space of ten Hours, and the latter in
    Twenty-one and an Half so that the Squares of
    their periodical Times, are very near in the same
    Proportion with the Cubes of their Distance from
    the Center of Mars which evidently shows them to
    be governed by the same Law of Gravitation, that
    influences the other heavenly Bodies.
