Asgard is the second largest multi-ringed basin (large impact crater) on Jupiter's moon Callisto.[2] It is named after Asgard, the realm of the gods in Norse mythology. The central part of Asgard is dominated by the domed Doh impact crater.
A smaller multi-ring structure is superposed on the northern part of Asgard. It is called Utgard (also from Norse mythology) and measures around 600 km (370 mi) in diameter.[2] Utgard is the fourth largest multi-ring feature on Callisto. A substantial part of the central region of Utgard is covered with deposits from the relatively young Burr crater.
