Description
Enwonwu crater on Mercury. The feature indicated by the white arrow in this NAC (Narrow Angle Camera) image is the newly named crater Enwonwu. It is named in honor of Benedict (Ben) Chukwukadibia Enwonwu, the twentieth century modernist Nigerian sculptor and painter. Enwonwu crater displays a central peak and a set of bright rays emanating from the crater rim. The rays cross the surrounding surface and neighboring craters, indicating that Enwonwu crater was formed comparatively recently in Mercury's history. The brightness of the rays also suggests relative youth, as over time rays darken and disappear on Mercury's surface. These relationships provide useful indicators for determining the relative ages of features and the sequence of events that have shaped the surface of Mercury.
