Dimorphos asteroid seen by DART

DART's last complete image of the Dimorphos asteroid before impact. It was taken when the spacecraft was about 12 km from the asteroid and two seconds before impact. Dimorphos, at 160 m across is about the same size as the Great Pyramid of Giza. Its surface is covered with large boulders, the largest of them house-sized. The current estimate is there is about 1 000 tonnes of debris on the surface in all, enough to fill 60 train carriages.
