Facts about Miranda

  • Miranda was discovered in 1948 by astronomer Gerard Kuiper. The Kuiper Belt of the outer solar system is named for him.
  • Miranda is made largely of ice with some rocky material closer to its centre.
  • No two surface areas on Miranda are alike. Its topography ranges from cliffs to craters, and tectonic features.
  • Verona Rupes is the largest cliff in the solar system. It rises up some 20 kilometres above the surrounding landscape. It may have formed when the surface faulted and cracked, causing part of it to drop.
  • Miranda’s surface has several tectonic regions that look like raceways called coronae. One of them has a “checkmark” shaped feature in the centre.
  • Miranda is one of the smallest bodies in the solar system to be self-rounded under its own gravity.
  • Miranda has experienced geological activity that was likely caused by tidal heating when this little moon was in orbital resonance with its neighbour Umbriel.
  • The Voyager 2 spacecraft is the only mission to fly close enough to image Miranda. There are no other missions to Miranda planned at this time.
