Aratus CA (lat. 24.5 N, long. 11.3 E) is an irregular-shaped crater 8.6 km long by 3 km wide in western Mare Serenitatis, which was photographed during the Apollo 15 and 17 missions. It is similar in form to Bear Crater (fig. 30-2), a small volcanic vent formed in Holocene basalt flows of the Snake River Plains, Idaho. The two features are compared and it is concluded that Aratus CA may have a geologic structure and history similar to that of Bear Crater.
