Mercury’s Peak-Ring Basins

Mercury’s Peak-Ring Basins
Two prominent basins, Chekhov at the upper left and Schubert at lower right, are both just under 200 km in diameter but have very different appearances. Chekhov has a prominent peak ring and its older age is reflected in the numerous craters that have battered its rim and floor. Schubert's floor is smooth with only a hint of its peak ring peeking through.
