Description
Wikipedia
Additional Information
- IAU page: Aratus CA
- Although Aratus CA is basically a rimless depression, it can be seen as a bright dot when the sun is very low to the west. It would appear that the Sun's setting rays are able to shine down [/Vallis%20Christel Vallis Christel] and strike the east wall of the pit between [/Vallis%20Krishna Vallis Krishna] and [/Rima%20Sung-Mei Rima Sung-Mei]. - JimMosher JimMosher
Nomenclature
- This is regarded as a [/satellite%20feature satellite feature] and hence is named for the "parent" crater, [/Aratus Aratus], even though it is at a considerable distance and unrelated to it.
- There is considerable confusion regarding the nomenclature of this feature. On several of the [/DMA DMA]-prepared NASA maps it is given the provisional name "Lorca" (used as the title for the Topophotomap sheets), and on two of the LM-series maps this name is even listed as "approved by the IAU". But it appears this is a clerical error and the name Lorca (an apparent reference to the Spanish writer) was [/Invalid%20Names never approved]. - JimMosher JimMosher
- The naming of sub-components of a named feature is rather unusual.
- Aratus CA is called Krishna on chart 23 in Antonin Rukl's Atlas of the Moon.- DannyCaes DannyCaes May 26, 2010

Bibliography
- Greeley, R. (1976). Photogeology of Aratus CA, Mare Serenitatis. Abstracts of the Lunar and Planetary Science Conference 7 (2): 331. (Note: Greeley refers to the central pit as "Lorca" -- an impression he probably got from the placement of the label for that unapproved substitute name for Aratus CA on the topographic maps)
