![]() Names were questionable because the names are not shown in the sources, or there isĬonflicting information in the sources. The location of each name wasĮxamined, sometimes in multiple sources, before inclusion. Substantial effort has been made to accurately place each name. Process is also described in the gazetteer. Recorded in the "News" section on the title page of the gazetteer. ![]() That change will be shown on the corresponding map, and a ![]() ![]() Whenever there is a change to the lunar portion of the Gazetteer of Planetary Nomenclature, If a name is dropped, it will be removed, and if aįeature is renamed, the new name will replace the old name. This is not a complete record of cross references, only those discovered during the research for these maps. Cross references between these old and new names have been noted in the "Additional Information" field of the gazetteer. Informal names and names that have been changed are not shown. Over the decades, many informal names have been used on the Moon and some IAU-approved names have been officially changed. The lettered crater names included in the Gazetteer of Planetary Nomenclature, and therefore in this atlas, are found in the definitive source "NASA Catalogue of Lunar Nomenclature" (NASA Reference Publication 1097). The maps shown here include only names that are formally approved by the IAU and are currently in use. These names are of various feature types: catenae, craters, dorsa, fossae, lacūs, landing site names, maria, montes, oceanus, paludes, planitiae, promontoria, rimae, rupēs, lettered craters (called "satellite features" in the gazetteer), sinūs, and valles. Maintains the Gazetteer of Planetary Nomenclature on behalf of the IAU with funding from the National Aeronautics and Space Administration (NASA).Īt the time of this writing, there are 9,003 IAU-approved names in use on the Moon (not including names that have been dropped but are retained in the gazetteer for reference). The Astrogeology Science Center of the U.S. Of Planetary Nomenclature, which is a dynamic listing of IAU-approved planetary surfaceįeature names. Web site are based on the information contained in the Gazetteer Internationally recognized authority for assigning nomenclature to planetary surface features. The International Astronomical Union (IAU) is the As new names are approved, they are added to the maps so users have access to the most recent changes in lunar nomenclature. The purpose of the lunar maps presented here is to provide an up-to-date and comprehensive depiction of lunar nomenclature.

The imaging operations center is based at the Space Science Institute in Boulder, Colo.įor more information about the Cassini-Huygens mission visit. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. Image scale is 5 miles (8 kilometers) per pixel. The view was obtained at a distance of approximately 870,000 miles (1.4 million kilometers) from Atlas. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 16, 2012. See Atlas and the F Ring and Saturn's Saucer Moons for other views of Atlas (19 miles, 30 kilometers across). ![]() This view looks toward the northern, sunlit side of the rings from just above the ringplane. The main rings are closer to the spacecraft than Atlas is, and the moon appears as only a small, white dot in the center of the image. The Cassini spacecraft looks past Saturn's main rings to spy the tiny moon Atlas, which orbits between the main rings and the thin F ring. ![]()
