Voyager 1 image of Valhalla, a multi-ring impact structure 3,800 km in diameter. The largest impact features on Callisto's surface are multi-ring basins. [13] [61] Two are enormous. Valhalla is the largest, with a bright central region 600 km in diameter, and rings extending as far as 1,800 km from the center (see figure). [63]
