Diana Craterlet lies in north Mare Tranquillitatis on the lunar near side with the northeastern quadrant's Grace Craterlet and Mons Esam as nearest named neighbors.
Diana is centered at 14.29 degrees north latitude, 35.65 degrees east longitude, according to the International Astronomical Union's (IAU) Gazetteer of Planetary Nomenclature. The northern hemisphere craterlet achieves its northernmost and southernmost latitudes at 14.31 degrees north and 14.27 degrees north, respectively. The northeastern quadrant craterlet maintains its easternmost and westernmost longitudes at 35.68 degrees east and 35.63 degrees east, respectively. Diana has a diameter of 1.55 kilometers.
Diana Craterlet is located toward the northern edge of Mare Tranquillitatis. The dark, basaltic plain primarily occupies the near side's northeastern quadrant but crosses the equator for southernmost reaches into the southeastern quadrant.
Mare Tranquillitatis ("Sea of Tranquility") is centered at 8.35 degrees north latitude, 30.83 degrees east longitude. The eastern hemisphere mare ("Latin: "sea") reaches to 19.37 degrees north and minus 4.05 degrees south for its northernmost and southernmost latitudes, respectively. The dark plain's easternmost and westernmost longitudes stretch from 45.49 degrees east to 16.92 degrees east, respectively. Mare Tranquillitatis has a diameter of 875.75 kilometers.
Grace lies as the nearest named crater to Diana in northern Mare Tranquillitatis. Grace is situated to the near southeast of Diana.
Grace is centered at 14.21 degrees north latitude, 35.89 degrees east longitude. The craterlet finds its northernmost and southernmost latitudes at 14.23 degrees north and 14.18 degrees north, respectively. It posts easternmost and westernmost longitudes of 35.92 degrees east and 35.87 degrees east, respectively. Grace has a diameter of 1.49 kilometers.
Mons Esam resides as Diana's nearest named northeastern neighbor. The mountain makes an isolated rise in northern Mare Tranquillitatis.
Mons Esam is centered at 14.61 degrees north latitude, 35.71 degrees east longitude. The mountain establishes its northernmost and southernmost latitudes at 14.74 degrees north and 14.48 degrees north, respectively. It marks its easternmost and westernmost longitudes at 35.77 degrees east and 35.65 degrees east, respectively. Mons Esam's diameter measures 7.92 kilometers.
Diana lies somewhat midway between Lucian and Vitruvius G. Lucian is positioned to the east of Diana. Vitruvius G, which occurs as the easternmost and southernmost of the Vitruvius Crater system's six satellites, is located to the southwest of Diana.
Lucian is centered at 14.34 degrees north latitude, 36.78 degrees east longitude. The northern Mare Tranquillitatis crater obtains northernmost and southernmost latitudes of 14.45 degrees north and 14.23 degrees north, respectively. It places its easternmost and westernmost longitudes at 36.9 degrees east and 36.67 degrees east, respectively. Lucian Crater's diameter measures 6.85 kilometers.
Vitruvius G is centered at 13.89 degrees north latitude, 34.61 degrees east longitude. The Vitruvius Crater system's easternmost and southernmost satellite records northernmost and southernmost latitudes of 13.97 degrees north and 13.81 degrees north, respectively. It registers easternmost and westernmost longitudes of 34.69 degrees east and 34.52 degrees east, respectively. Vitruvius G's diameter measures 4.99 kilometers.
Maraldi W is positioned to the southeast of Diana and of Grace. Maraldi W occurs as the southernmost of the Maraldi Crater system's seven satellites. Maraldi W anchors the southern point of a triangle with Vitruvius G and Lucian as northwestern and northeastern vectors, respectively.
Maraldi W is centered at 13.17 degrees north latitude, 36.09 degrees east longitude. The Maraldi Crater system's southernmost satellite is credited with northernmost and southernmost latitudes of 13.22 degrees north and 13.13 degrees north, respectively. Its easternmost and westernmost longitudes are identified as 36.16 degrees east and 36.02 degrees east, respectively. Maraldi W has a diameter of 4.22 kilometers.
Diana numbers among 95 minor features identified with first-name designations on lunar topophotomaps prepared and published by The Defense Mapping Agency (DMA) for the National Aeronautics and Space Administration (NASA). Diana is plotted on NASA Lunar Topophotomap 61A2S1, which was published in January 1976. The map's Names Information lists "Diana, Grace, Mons Esam" as unofficial names used "only for the identification of features on this map."
The International Astronomical Union approved Diana as the craterlet's official name in 1979. The Gazetteer of Planetary Nomenclature explains Diana as: "Latin female name."
