Description

Here is a little Copernicus made ​​under conditions conducive lighting, the sun was pin on it, then do not show shadows.

Copernicus is a prominent impact crater located in the east of Oceanus Procellarum. Copernicus's age is estimated at about 800 million years, the time that marks the beginning of the time of Copernicus in the lunar geologic time scale. Due to its relative youth, the crater received very little erosion and remains sharp and well defined.

The circular rim has a discernible hexagonal shape, with an inner wall and a terrace of 30 km of walls, large and slanted, which falls about a mile to the sea environment. There are three terraces visible and distinct arch shaped due to slippage of the rear inner wall.

Most likely due to their recent formation is that the crater floor was not flooded by lava. The terrain along the bottom half is mountainous in the south while the north is relatively mild. The central peaks consist of three isolated mountain climbing where the maximum measured 1.2 km above the ground. These peaks are separated from one another by valleys, and forms a coarse thread along an east-west axis. Infrared observations of these peaks during the 1980s found that they were mainly composed of mafic form of olivine.

The rays of the crater Copernicus spread up to 800 km in the sea all around, overlapping the rays of craters Aristarchus and Kepler. The spokes are less distinct and longer than the radii linear crater Tycho in turn cloudy forming a pattern with markers plumy. An extensive pattern of small secondary craters can also be observed around Copernicus, a detail that was described in a map of Giovanni Cassini in 1680.
