Why it matters

Herschel shows how an impact structure can become the dominant visual fact of an entire moon.

What happenedA giant crater on Saturn's moon Mimas, so large it nearly defines the small world's appearance.

事实

  • The crater diameter is a significant fraction of Mimas itself.
  • Its central peak is especially visible in images.
