Mechnikov is an impact crater on the far side of the Moon. It is located just to the northeast of the much larger walled plain Galois, being separated by a stretch of irregular terrain about 20–30 km in width.
This is a roughly circular crater that has undergone a moderate amount of impact erosion, but is still relatively intact. Attached to the exterior along the northeast are the satellite craters Mechnikov C and Mechnikov D. There is a small crater in the western part of Mechnikov's interior floor.
A small crater along the northeast rim of Galois has a small ray system. Ray material from this crater crosses the interior of Mechnikov in a series of streaks that are radial to the impact, producing a fan-like appearance.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Mechnikov.
