Cauchy is a small lunar impact crater on the eastern Mare Tranquillitatis. It is circular and symmetric, with a small interior floor at the midpoint of the sloping inner walls. Due to the high albedo of this bowl-shaped formation, it is particularly prominent at full Moon. Just to the northeast of the rim of this crater is the wide rille named Rima Cauchy, a 210-kilometer-long cleft following a line to the northwest.
Southwest of Cauchy is a 120-km fault in the surface named the Rupes Cauchy. This wall parallels the Rima Cauchy to the northwest. South of Rupes Cauchy are two lunar domes designated Omega (ω) Cauchy and Tau (τ) Cauchy. They lie to the south and southwest of Cauchy respectively. Each lunar dome has a tiny craterlet at its crest.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Cauchy.
