  description = """
  Mercury is the first planet from the Sun and the smallest in the Solar System.
  It is classified as a terrestrial planet, with roughly the same surface gravity
  as Mars. The surface of Mercury is heavily cratered, as a result of countless
  impact events that have accumulated over billions of years. Its largest crater,
  Caloris Planitia, has a diameter of 1,550 km (960 mi), which is about one-third
  the diameter of the planet (4,880 km or 3,030 mi).
