presents Doppler Farside Directory - Ridge Section 133

BRIEF DESCRIPTION
12.6_S_159.6_W 
Doppler is a 110 km lunar impact crater just to the left of center in Section 133 and named after Christian Doppler. It is located at the southern edge of the giant walled plain Korolev, on the farside of the Moon.  Doppler almost gets lost in the region map below Korelev (423 km, Section 122) but is of obvious characteristics in the near center. To the NE of Doppler is Korolev M. To the east are the craters Das and Galois. Farther to the southwest of Doppler is Mohorovicic (out of frame). The rim of Doppler has a somewhat polygonal form, and a smaller crater is joined with the inner side of the northeast wall. The interior of Doppler is rough and irregular, with some terracing of the worn outer walls, and a complex of central hills to the north of the midpoint. The crater Doppler B lies within the northern rim, and occupies a portion of the northern floor. A small, crater-formed valley runs to the southeast across the floor of Doppler from the rim of Doppler B.
