EponymJean P. F. Blanchard

Blanchard is alunarimpact crater that lies on thefar side of theMoon, just behind the southwestern limb. It lies to the south-southwest of the craterArrhenius, and northwest ofPilâtre. Further to the south is the rugged terrain to the north of the walled plainHausen.

This crater was named after French aeronautJean-Pierre Blanchard by theIAU in 1991.[1] It was previously known as Arrhenius P.

The rim of Blanchard is worn and rounded, with a slight elongation along a northeastern direction. There is a break in the northwest rim. The two crater formations have nearly merged, and share the same interior floor. The remainder of the rim has several other breaks caused by impacts, particularly along the southeastern rim. The interior floor, although somewhat rough, does not contain a central peak or notable features.

This crater lies within theMendel-Rydberg Basin, a 630 km wide impact basin ofNectarian age.
