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.

Satellite craters

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.
