Why it matters

Odysseus anchors the Saturn branch as a giant crater on an icy body: scale, preservation, and clear form.

What happenedOne of Tethys's largest craters, comparable in scale to the visual identity of the moon itself.

الوصف العلمي

On small icy bodies, huge impacts can create structures occupying a large fraction of the disk and shaping how relief is read afterward.
