Move your mouse over the picture to see the names of the various craters.
Petavius is the largest crater here and is 177 Km in diameter and 3300 metres deep with central mountains rising to 1700 meters. There are a number of rilles on its floor, the most obvious is a massive cleft running from the central mountain to the western wall. This is a good example of a floor-fractured crater which tend to be large craters on the margins of maria. Another interesting feature in this picture is the Vallis Palitzsch. It is formed by three overlapping craters and dates from about 3,900 million years ago.
The scale markers are approximately 100 Km north and west.
The picture was taken with a ToUcam attached to my LX200 on 16th November 2005 at 20:57 UT,
when the Moon was 15.5 days old.
