(Redirected from Burr (crater))
Callistoan multi-ringed impact basin
In this Galileo image, Asgard is centered in the pale region, just to the upper right of the image center, with surrounding concentric rings. Utgard is a smaller multi-ring structure superposed on the northern part of Asgard. The bright features are more recent impact craters, including Burr near the top, Tornarsuk at right, Njord below Tornarsuk, and Omolʹ above Tornarsuk to the right of Burr
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. 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.
