Summary

DescriptionGuericke S and J craters hrp217.jpg	English: Guericke S and J craters, northeast of Guericke, on the moon. This is Figure 229 of Apollo Over the Moon (NASA SP-362, 1978), which has the following caption: This 18-km-long "figure 8" pair of noncircular craters near the crater Guericke probably was not formed by hypervelocity impacts of bodies from space. It could be a secondary impact feature formed by projectiles from the Imbrium 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 the mare 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. -D.E.W.
