Triesnecker is a prominent lunar impact crater that is located in the Sinus Medii, near the central part of the Moon's near side and is named after Franz de Paula Triesnecker. It is located more than 100 km north-northwest of the crater Rhaeticus, about 95 km west of Dembowski, and to the east-southeast of the flooded Murchison (about 80 km) and its smaller Chladni (about 55 km).
Its diameter is 26 km long and is 2,800 meters deep. Also, the area is around 500 km² and the perimeter is around 80 km.
Also the sun rises just during or after the third quarter of Earthshine and the sun sets just during or after its first quarter.
The crater rim of Triesnecker is somewhat distorted from a circular shape, having a notable bulge in the western wall, and lesser rises in the southeastern and northeastern rims. The inner walls are terraced and the interior is somewhat rough, with a central peak at the midpoint. Triesnecker has a ray system that is most prominent when the sun is at a high angle. The rays extend over 300 kilometers.
To the east of this crater is an extensive system of rilles extending over an area 200 kilometers across, running generally north–south. These were likely created by tectonic forces beneath the surface. Beyond, to the northeast, is the Rima Hyginus valley, with the crater Hyginus at the midpoint.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Triesnecker. Triesnecker D, F and G are to the southeast, Triesnecker E is to the north-northwest and Triesnecker H and J are to the west-southwest.
