Tycho is a striking crater in the southern plateaus of the Earth-facing side of the moon. Its center is at 43.3 ° south selenographic latitude and 11.2 ° west longitude , near the Mare Nubium . Its diameter is 85 kilometers. Its depth is remarkably pronounced in comparison with the proportions of other lunar craters and measures 4850 meters from the heights of the crater wall. The inner slope of the wall is terraced and has a slope of 34 degrees. The outer slope is inclined 26 degrees. Solidified lava flows can be seen on the slopes and on the crater floor. From the crater floor, a central mountain range, known as a rising central peak , up to an altitude of at least 1600 meters.
Tycho has a very bright interior and is also the center of the brightest and most extensive ray system on the moon, which covers a large part of the front and makes it the most famous ray crater. The landing site of Apollo 17 was on one of the Tycho beams . In addition, Apollo 20 should land in the crater. Based on the samples of the powdery and mainly glass bead-like material that were brought to earth, the age was determined to be around 100 million years and its formation was supported by the ejection of a large explosive impact at the site of Tycho.
