Guericke (crater)

Guericke is the remnant of alunarimpact crater at the north part of theMare Nubium. It is named after German scientistOtto von Guericke.[1] To the north-northwest lies the largeFra Mauro crater, along with the co-joined cratersParry andBonpland. To the east are the cratersKundt andDavy.

Guericke S and J craters. This 18-km-long "figure 8" pair of noncircular craters probably was not formed by hypervelocity impacts of bodies from space. It could be asecondary impact feature formed by projectiles from theImbrium basin 700 km to the north. The terrace at the base of the crater walls could be debris from the walls or a "bathtub ring" left by a formerly higher stand of themare fill. Alternatively, the crater pair and the terrace could have been formed by volcanic eruptions. The superposed bright crater is younger than and unrelated to either the "figure 8" pair or the mare.

The surviving rim of Guericke has been worn, battered, and partly submerged by thebasalticlava that covers the floor. The wall is now little more than a circular series of ridges that join with rises that flow to the north, northwest, and south. The flooded crater remnant Guericke F is attached to the southwest exterior. The interior flood has a few small rises in the otherwise nearly flat surface. Two craters (Guericke D and H) mark the floor in the southwest quadrant.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Guericke.
