Close-Up of Tycho's Central Peak

Close-Up of the Central Peak
The view shows the steep slopes and rugged top of Tycho's central peak. One astonishing detail is the large boulder—100 by 120 meters (330 by 400 feet)—perched near the top and resting on the impact melt that coats the summit. How did it get there? Perhaps it was ejected straight up and then landed just after the peak formed.
