Unknown
One of the craters that I love to watch on the northern Moon is Pythagoras, for its oval shape as seen from Earth because it is located on the edge of the lunar disk, but also for interior terraces and peaks in its center, features that make it a special crater when seen through an astronomical telescope.
The crater has an oval appearance due to the oblique angle of observation. For this reason, only the western interior can be seen from Earth.
Pythagoras (130 km), has a depth of 5 km and is a prominent crater compared with those in its vicinity, and that because it is very well preserved. It has a system of wide terraces. Although generally circular, the outer edge is hexagonal. The floor is smooth but with a hilly area. Central peaks reach a height of 1500 m.
In front of Pythagoras, we see a large crater named Babbage (143 km), one with a depth of 2 km.
The remnant crater named South, is entered in its southeastern floor.
Babbage's outer wall was eroded and modified by other multiple impacts until all that was left of it was a ring of rounded hills. Over the southern edge is observed Babbage E (68 km), whose northern edge is practically nonexistent forming a kind of golf within Babbage.
Oenopides (67 Km.) is a lunar crater that is located on the northwestern edge of the Moon, and therefore appear oblong when viewed from Earth. Is adjoining southeast to the crater Babbage E.
Oenopides is an old crater which has been heavily eroded by subsequent impacts, leaving a lower outer edge. There is a gap in the south-east and the interior is attached to the Mare Frigoris's south. The bottom is marked by small craters crater.
Crater name comes from Oenopides of Chios, which was an ancient Greek mathematician and astronomer, who lived about 450 BC in He was born shortly after 500 BC Chios island and worked in Athens.
Craters were filmed with a video camera attached to an astronomical 203 mm Newtonian telescope.
In the picture below are labeled craters and other lunar features in the region. To better understand this photo, you should note that the label with the name or the letter of larger craters could be found at their center, and on the small craters, you should find them around them, usually above.
