Bessel is a small impact crater in the southern half of the Mare Serenitatis , north-northeast of the Menelaus crater . Despite its small size, it is the only crater that lies entirely within the mare .
The circular, bowl-shaped crater has a higher albedo in its crater rim than the surrounding lunar surface. The rim shows no noticeable signs of erosion , and the interior of the crater has no noticeable features, apart from a few slipped heaps of rubble. Due to its small size, the terraces common in larger craters could not develop near Bessel.
On the western flank, Bessel is passed by a large ray structure that runs from north to south over the surface of the Mare and obviously starts from Tycho .
