Sylvester is a lunar impact crater that is located near the north pole of the Moon, along the northern limb in the libration zone. It lies just to the south-southeast of the Hermite crater, which is within one crater diameter of the pole. South of Sylvester is the Pascal crater. Due to the location of this crater, it only receives sunlight at a low angle.
This crater is generally circular, with a sharp-edged rim that has only received a moderate amount of wear. There are no craters of note along the rim, although Sylvester intrudes into a smaller, shallow-rimmed crater to the southeast. The interior floor is relatively flat, but puctuated by several tiny craters. At the mid-point is a small central peak.

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 Sylvester crater.
