Chevallier Crater parents four satellites on the lunar northeast near side in proximity to middle-latitude lunar mare Lacus Temporis (Lake of Time).

The Chevallier crater system's parent is centered at 45.01 degrees north latitude, 51.57 degrees east longitude, according to the International Astronomical Union’s (IAU) Gazetteer of Planetary Nomenclature. The lava flooded lunar impact crater's northernmost and southernmost latitudes reach 45.86 degrees north and 44.15 degrees north, respectively. The middle-latitude crater's easternmost and westernmost longitudes extend to 52.78 degrees east and 50.36 degrees east, respectively. Chevallier Crater's diameter spans 51.83 kilometers.

The Chevallier crater system of parent and four satellites claims Lacus Temporis as nearest lunar mare. Chevallier Crater neighbors to the near southwest of the double-lobed, dark, basaltic plain.

One of the crater system's four satellites, Chevallier B, occurs as an internal satellite, lying within its parent's borders. Chevallier K and Chevallier M reside to the south-southwest and near north, respectively, of their parent. Chevallier F lies to the east as a resident of Lacus Temporis.

Chevallier B lies off-center, to the east of the midpoint of its parent's lava-flooded interior floor. The internal satellite is centered at 45.15 degrees north latitude, 51.96 degrees east longitude. It obtains northernmost and southernmost latitudes of 45.35 degrees north and 44.96 degrees north, respectively. Its easternment and westernmost longitudes are found at 52.24 degrees east and 51.68 degrees east, respectively. Chevallier B's diameter measures 12.05 kilometers.

Chevallier M has merged with projections of its parent's northern rim. The double crater is centered at 46.04 degrees north latitude, 51.16 degrees east longitude. Chevallier M posts northernmost and southernmost latitudes of 46.31 degrees north and 45.77 degrees north, respectively. It marks its easternmost and westernmost longitudes at 51.55 degrees east and 50.78 degrees east, respectively. Chevallier M's diameter of 16.27 kilometers qualifies it as the largest of the Chevallier crater system's four satellites.

Atlas A's location as the most easterly of the Atlas crater system's eight satellites places it in proximity to Chevallier Crater and Chevallier M. Atlas A is centered at 45.34 degrees north latitude, 49.56 degrees east longitude. Its northernmost and southernmost latitudes occur at 45.71 degrees north and 44.97 degrees north, respectively. Its easternmost and westernmost longitudes register at 50.08 degrees east and 49.04 degrees east, respectively. Atlas A's diameter measures 22.22 kilometers.

Chevallier K is located to the south-southwest of its parent. It finds its northernmost and southernmost latitudes at 43.61 degrees north and 43.42 degrees north, respectively. It obtains easternmost and westernmost longitudes of 50.99 degrees east and 50.74 degrees east, respectively. Chevallier K's diameter of 5.56 kilometers qualifies it as the smallest of the Chevallier crater system's four satellites.

Chevallier K resides in proximity to Shuckburgh Crater and its attached satellite, Shuckburgh C. Shuckburgh Crater lies to the east-southeast of Chevallier K. Shuckburgh C's connection to an outward projection in its parent's northern rim positions it to the east of Chevallier K.

Shuckburgh Crater is centered at 42.65 degrees north latitude, 52.71 degrees east longitude. The worn, lava-flooded lunar impact crater marks northernmost and southernmost latitudes at 43.27 degrees north and 42.03 degrees north, respectively. It lists easternmost and westernmost longitudes of 53.56 degrees east and 51.87 degrees east, respectively. Shuckburgh Crater's diameter spans 37.73 kilometers.

Shuckburgh C, the only parentally-attached satellite of the Shuckburgh crater system's three satellites, is centered at 43.54 degrees north latitude, 52.72 degrees east longitude. Its northernmost and southernmost latitudes occur at 43.73 degrees north and 43.35 degrees north, respectively. It achieves easternmost and westernmost longitudes of 52.98 degrees east and 52.46 degrees east, respectively. Shuckburgh C's diameter measures 11.58 kilometers.

Chevallier F's location in the northern lobe of Lacus Temporis qualifies it as the most easterly of the Chevallier crater system's four satellites and also as the most distanced satellite from the system's parent. Chevallier F claims northernmost and southernmost latitudes of 46.34 degrees north and 46.06 degrees north, respectively. It gives easternmost and westernmost longitudes of 56.8 degrees east and 56.39 degrees east, respectively. Chevallier F has a diameter of 8.53 kilometers.

Chevallier F pairs with a small, cup-shaped crater to its north-northeast as conspicuous landmarks at the intersection of the Lake of Time's two lobes. Lacus Temporis is centered at at 46.77 degrees north latitude, 56.21 degrees east longitude. The small lunar mare's northernmost and southernmost latitudes span 49.36 degrees north to 43.81 degrees north, respectively. Its easternmost and westernmost longitudes extend to 60.56 degrees east and 52.13 degrees east, respectively. Lacus Temporis measures 205.3 kilometers.

The takeaways for Chevallier Crater's parentage of four satellites on the lunar northeast near side are that Chevallier Crater resides as a near southwestern neighbor of Lacus Temporis (Lake of Time); that Chevallier B occurs as the Chevallier crater system's only parental occupant; that Chevallier M, attached to its parent's northern rim, qualifies as the largest of the crater system's four satellites; that Chevallier K, positioned to its parent's south-southwest, qualifies as the smallest of the crater system's four satellites; and that the Chevallier crater system's most distant satellite, Chevallier F, lies in the Lake of Time's northern lobe and pairs with a small crater to its north-northeast as markers of the juncture of the small lunar mare's two lobes.
