Directly Above Giordano Bruno
The crater is about 21 kilometers (13 miles) across. Rock melted by the impact collected in pools on the crater floor as much as 3 kilometers (2 miles) below the rim of its steep walls. In some places on the crater floor (middle) you can see where molten rock overtopped some features and flowed downhill before solidifying.
