Bianchini is a lunar impact crater that lies along the northern Jura Mountains that ring the Sinus Iridum, in the northwestern part of the near side of the Moon.

[1] The impact of this crater near the edge of the Jura Mountains deposited some material into the Sinus Iridum floor.

Within the inner wall is a somewhat irregular floor and a small cluster of ridges at the midpoint.

Portions of the inner wall have slumped toward the floor along the northern edges.

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