The rim of this crater is generally circular, but with some irregularities. There is a small outward bulge in the rim to the east-southeast, and an inward bulge on the opposite face. There is also a slight outward bulge along the north rim. The satellite crater Blazhko F is attached to the exterior of the east rim. The inner wall along the northeast face is striated with terraces. The interior floor is relatively level.

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