Krieger is a lunar impact crater on the eastern part of the Oceanus Procellarum. It is located to the north-northwest of the flooded crater Prinz, and north-northeast of the prominent ray crater Aristarchus. To the northwest lies the small Wollaston. The crater was formally named in 1935.[1]
In the past the floor of Krieger has been flooded by basaltic lava, leaving only a low, circular, somewhat polygonal ridge formed by the rim. The southern rim is broken across by the small Van Biesbroeck, and there is a small gap in the western rim. A meandering rille leads away from this break toward the northwest.
Krieger is a crater of Upper (Late) Imbrian age.[2]
Nearby craters
[edit]Two tiny craters next to the eastern rim have been designated Rocco and Ruth. Rocco was previously designated as Krieger D before being named by the IAU.
| Crater | Longitude | Latitude | Diameter | Name source |
|---|---|---|---|---|
| Rocco | 28.9° N | 45.0° W | 5 km | Italian masculine name |
| Ruth | 28.7° N | 45.1° W | 3 km | Jewish feminine name |
The nearby surface to the southwest contains a number of rilles belonging to the Rimae Aristarchus and Rimae Prinz rille systems. Further to the east-southeast are the Montes Harbinger mountains.
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 Krieger.
