Coniraya (crater)

Coniraya is a large, shallow crater on the dwarf planet Ceres. It is the namesake for the Coniraya Quadrangle.

Naming
The crater is named after the Incan lunar and fertility deity, Coniraya Viracocha (Kon Iraya Wiraqocha), who came to earth at Huarochirí (Waruchiri), and created villages, terraced fields and irrigation canals. The name was officially approved by the International Astronomical Union (IAU) on 3 July 2015.

Geology
Coniraya is an unusually shallow crater; despite having a diameter of roughly 135 kilometers, it is only 500 meters deep. This is in contrast to the neighboring crater Vinotonus, which is similar in size and age yet ten times deeper. The shallow depth of Coniraya may have been caused by viscous relaxation, though only if Ceres's crust at the impact site was unusually enriched in water ice. The impact which created Coniraya was caused by a large body travelling an unusually low speed. Coniraya is estimated to be approximately 1.3 billion years old despite its degraded state.
