The six-member Roche Crater system comprises parent crater Roche and four satellites occupying the cratered terrain to the south of Mare Ingenii in the lunar far side's southern hemisphere.
Roche Crater, the system's parent, is centered at minus 42.37 degrees south latitude, 136.54 degrees east longitude, according to the International Astronomical Union’s (IAU) Gazetteer of Planetary Nomenclature. Its northmost and southmost latitudes extend from minus 39.85 degrees south to minus 44.88 degrees south, respectively. Its eastmost and westmost longitudes end at 139.96 degrees east and 133.12 degrees east, respectively. Roche Crater's diameter spans 152.67 kilometers.
Roche B nestles on its parent's craterlet-notched, northeastern inner wall. Roche B is centered at minus 40.58 degrees south latitude, 137.79 degrees east longitude. The southern hemisphere satellite expresses its northmost and southmost latitudes at minus 40.22 degrees south and minus 40.94 degrees south, respectively. It extinguishes its eastmost and westmost longitudes at 138.27 degrees east and 137.71 degrees east, respectively. Roche B's diameter measures 21.90 kilometers.
Roche C resides to the northeast of its parent and Roche B. Roche C is centered at minus 39.13 degrees south latitude, 139.89 degrees east longitude. The southern hemisphere satellite finds its northmost and southmost latitudes at minus 38.85 degrees south and minus 39.41 degrees south, respectively. It finalizes its eastmost and westmost longitudes at 140.26 degrees east and 139.53 degrees east, respectively. Roche C has a diameter of 16.98 kilometers.
Roche V and Roche W lie to the northwest of their parent crater. Roche V neighbors to the near west of Roche W.
Roche V is centered at minus 38.98 degrees south latitude, 129.99 degrees east longitude. The southern hemisphere satellite obtains its northmost and southmost latitudes at minus 38.59 degrees south and minus 39.36 degrees south, respectively. Its eastmost and westmost longitudes occur at 130.52 degrees east and 129.46 degrees east, respectively. Roche V's diameter measures 27.81 kilometers.
Roche V's eastern neighbor, Roche W, is centered at minus 39.26 degrees south latitude, 131.26 degrees east longitude. The southern hemisphere satellite establishes its northmost and southmost latitudes at minus 38.91 degrees south and minus 39.60 degrees south, respectively. It finds its eastmost and westmost longitudes at 131.70 degrees east and 130.81 degrees east, respectively. Roche W's diameter measures 20.80 kilometers.
Roche B is positioned as the southernmost of the Roche Crater system's four satellites. Roche C qualifies as the easternmost member of the Roche Crater system. Roche V ranks as the westernmost member of the Roche Crater system. Roche V's close eastern neighbor places as the northernmost member of the Roche Crater system.
The diameters of the four satellites in the Roche Crater system range from 16.98 kilometers to 27.81 kilometers. Its diameter of 27.81 kilometers qualifies Roche V as the largest of the Roche Crater system's four satellites. Roche C's diameter of 16.98 kilometers classifies it as the smallest of the Roche Crater system's four satellites.
Rosseland Crater neighbors to the west of northwestern Roche Crater and south of satellites V and W. Rosseland formerly was designated as Roche U.
Rosseland Crater is centered at minus 40.82 degrees south latitude, 130.68 degrees east longitude. The lunar southern hemisphere-sited crater delimits its northmost and southmost latitudes at minus 39.72 degrees south and minus 41.92 degrees south, respectively. It defines its eastmost and westmost longitudes at 132.14 degrees east and 129.25 degrees east, respectively. Rosseland Crater's diameter spans 67.66 kilometers.
The Roche Crater system occupies the cratered terrain between Mare Ingenii, to the system's east, and Mare Australe, to the system's west. Mare Australe's sprawl across the moon's southeastern limb attains dual status as far side and near side resident for the lunar mare (Latin: mare, "sea"; plural, maria, "seas"). Contrastingly, Mare Ingenii confines its territory to the lunar far side.
Mare Ingenii (Sea of Cleverness) is centered at minus 33.25 degrees south latitude, 164.83 degrees east longitude. The southern hemisphere-sited dark, basaltic plain's northmost and southmost latitudes stretch from minus 28.54 degrees south to minus 37.42 degrees south, respectively. Its eastmost and westmost longitudes touch 169.85 degrees east and 158.55 degrees east, respectively. Mare Ingenii's diameter spans 282.20 kilometers.
Mare Australe (Southern Sea) is centered at minus 47.77 degrees south latitude, 91.99 degrees east longitude. The southern hemisphere-sited lunar mare's northmost and southmost latitudes reach minus 31.84 degrees south and minus 64.20 degrees south, respectively. It records eastmost and westmost longitudes of 113.36 degrees east and 70.43 degrees east, respectively. Mare Australe's diameter spans 996.84 kilometers.
The Roche Crater system memorializes 19th-century French astronomer, celestial mechanics specialist, mathematician and meteorologist Édouard Albert Roche (Oct. 17, 1820-April 27, 1883). The system's parent crater received official approval by the International Astronomical Union in 1970. The organization’s XIVth (14th) General Assembly was held in 1970 from Tuesday, Aug. 18, to Thursday, Aug. 27. The designations of the system's four satellites were adopted in 2006. The IAU's XXVIth (26th) General Assembly took place in 2006, from Monday, Aug. 14, to Friday, Aug. 25, in Prague, Czech Republic.

The organization’s XIVth (14th) General Assembly was held in 1970 from Tuesday, Aug. 18, to Thursday, Aug. 27, in the United Kingdom's East Sussex seaside town of Brighton.
Official approval of the names of the Roche Crater system's four satellites occurred in 2006. The IAU's XXVIth (26th) General Assembly was held in Prague, Czech Republic, in 2006 from Monday, Aug. 14, to Friday, Aug. 25.
