Why it matters

Menrva shows that crater scarcity is also scientific information: Titan's surface can hide and rework impact traces.

What happenedOne of Titan's few large craters, important because of the moon's dense atmosphere and active surface.

科学档案

Titan requires radar and infrared reading: crater morphology here is tied to atmosphere, precipitation, and organic materials.

研究历史

The name was adopted by the IAU in 2006; the feature is known from Cassini data and official nomenclature.

事实

  • Official diameter: about 392 km.
  • Titan has a dense atmosphere, making craters rare.
  • Menrva connects craters with the theme of active surfaces.
