Lomonosov is a lunar impact crater that is located just behind the western limb of the Moon.

The interior floor of Lomonosov has been resurfaced with lava flows, leaving a dark, level surface marked only by a few tiny craterlets and some streaks of ray material from Giordano Bruno.

Only the lowest portion of the interior is flooded, however, and much of the inner wall of the rim remains uncovered.

The inner wall is narrower along the northern edge where the crater overlies Maxwell.

[1] Lomonosov is a crater of Lower (Early) Imbrian age.
