eponym=Johannes Werner Werner is a prominent lunar
impact crater that lies in the rugged south-central highlands of theMoon . It is almost joined with Aliacensis crater to the southeast, and the pair form a rugged valley in the intervening gap. Due west of Werner is the distorted Regiomontanus crater, and to the north is the remains of the Blanchinus crater. It is from theEratosthenian period, which lasted from 3.2 to 1.1 billion years ago. The crater is named for15th century German mathematician and astronomerJohannes Werner ."Autostar Suite Astronomer Edition". CD-ROM. Meade, April 2006.]The rim of Werner crater shows little appearance of wear, and is much younger and less eroded that the other large craters in the surroundings. The interior wall is d, and there is a noticeable rampart on the exterior. There are several low rises on the crater floor and a notable central peak. Its highly terraced walls attain peaks of almost 1,500 feet. The crater is 45 miles (70 kilometers) in diameter, and the difference in height between its rim and its deepest parts is 4.2 kilometers.
