Enwonwu is a crater on the planet Mercury

Mercury (planet)

Mercury is the innermost and smallest planet in the Solar System, orbiting the Sun once every 87.969 Earth days. The orbit of Mercury has the highest eccentricity of all the Solar System planets, and it has the smallest axial tilt. It completes three rotations about its axis for every two orbits...

. It 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.
