What is "schneller"

Schneller is a lunar impact crater on the Moon's far side. It is located in the northern latitudes to the southwest of the crater Woltjer. This is a heavily worn and eroded crater that has a somewhat uneven rim with outward bulges to the southeast and northeast. The rim is nearly non-existent along the northwestern side. The interior of this crater is relatively featureless, with only a few small, indistinct craterlets.
