EponymJoseph Johann Littrow

Littrow is a lunar impact crater that is located in the northeastern part of the Moon's near side, on the east edge of Mare Serenitatis. Its diameter is 29 km. The crater is named after Bohemian astronomer Joseph Johann Littrow.[1] Some distance to the northeast is the prominent crater Römer, while to the south is Vitruvius.

The rim of Littrow is heavily worn and eroded, especially along the southern wall. The interior has been flooded with lava in the past, leaving a relatively smooth, featureless surface with no central rise.

Rimae Littrow[edit]

Just to the northwest of Littrow is a system of rilles designated the Rimae Littrow. These are located at selenographic coordinates 22.1° N, 29.9° E, and have a maximum diameter of 115 km. To the south-southwest is the Taurus–Littrow valley that is notable for being the landing site of the Apollo 17 mission. Two tiny craters to the west of this site have been assigned names by the IAU. These are listed below.

Satellite craters[edit]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Littrow.

D 23.7° N 32.8° E 8 km
F 22.0° N 34.1° E 12 km
P 23.2° N 32.8° E 36 km

The following craters have been renamed by the IAU.
