Why it matters

Pwyll matters as a compact but expressive object, showing how impact form changes on an active icy surface.

What happenedA Europa crater with bright ejecta that helps read impact processes in the icy shell of an ocean-world candidate.

Perfil científico

Bright ejecta and disrupted icy texture around the crater invite discussion of composition, ice reworking, and local surface history.

Datos

  • Official diameter: about 45 km.
  • The name comes from Celtic mythology.
  • Scientifically interesting because impact interacts with an icy shell.
