Goddard is a lunar crater that is located along the eastern limb of the Moon, and so is viewed from the edge from Earth. It is best viewed during favorable librations when the orientation of the Moon brings it further into sight. The crater is located in the Mare Marginis lunar mare, to the northeast of the prominent Neper crater. The Ibn Yunus crater remnant is attached to the southeastern rim, and is partly overlaid by Goddard. To the northeast is the Al-Biruni crater.
The crater rim of Goddard has nearly been destroyed along the southern edge, and the interior floor is connected to the surrounding mare through gaps in this section of the wall. The remainder of the rim is significantly eroded and worn, leaving only a ring of rugged ground surrounding the inner floor.
The floor of the crater has been resurfaced in the past by lava floods, leaving the interior nearly flat and featureless. There is no central peak and the mid-point, and only a few tiny craterlets mark the surface. The most prominent of these is a matched pair of small craterlets in the south-southwest part of the floor.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Goddard crater.
