Hayn

Photo achieved a great libration in latitude showing the mare humboldtianum in highlight.

The libration was so good that even the beautiful crater Hayn, Bel'kovich, Bel'kovich A and B are perfectly visible in its entirety, something that rarely occurs.

Hayn is a lunar impact crater that lies in the northeast of the Moon libration member in the zone. This location restricts the amount of detail that can be seen from the earth, thus Western inner side is permanently hidden from view. The observation of this crater can also be affected by libration so much that can be completely hidden from view.

This crater is located on the northwest edge of the walled plain Bel'kovich north of the mare humboldtianum.

This is a young crater, with a border and interior that has not been significantly eroded, is an exquisite example of a complex crater. It has a circular rim a little irregular and an interior wall that contains a number of terraces. The southern edge is slightly more pronounced at the time where it joins heavily worn edge Bel'kovich. There is also an outer wall beyond the edge that is more extensive to the southwest. The crater has a radius of system, and is therefore mapped as part of Copérnico system.

The interior floor is relatively stable compared to the ground around the crater. One of several ridges system are near the middle point inside with a broad valley in the north-south direction, which divides the break in the middle. There are also smaller side valleys, and all said there are a few dozen medium peaks. The rest of the floor also contains several small hills, especially to the west of the central peak.

The central peak complex in the image below obtained by LROC / NASA probe is dramatically lit by the low sun casting long shadows on the crater floor. The Hayn floor contains spectacular remains of the cause of the impact event.

In other full oblique image attached also LROC probe? NASA walls Hayn display the large terraces that formed the final phase of the crater formation, called modification stage. They are surface expression of concentric thrust listric failures. These faults develop when the transient cavity may gravitational collapse. The formation of terraces extends the cavity and shallow crater floors on the ground. This downward movement of the walls and the floor is followed by lifting in the center to accommodate the crust impact stress.
