Located on Comet 67P/Churyumov-Gerasimenko’s large lobe, Imhotep is a remarkably diverse region covering about 200 acres. It is one of the “most geologically diverse regions” observed by the Rosetta probe, according to the ESA, and an excellent place for studying the comet and how it formed.

In addition to an unusually flat swatch of real estate filled with fine-grained materials, Imhotep features many boulders (2,207 to be exact), rocky terrains, basins in which rocks and boulders have accumulated, fractured terraces indicative of internal layering, bright patches pointing to the presence of ice, and mysterious roundish features not seen elsewhere on the object. Comets, as Imhotep demonstrates, are far from boring.
