Nomenclature News

  • New Names for Montes and Undae on Titan

    The names of six montes (Angmar, Dolmed, Echoriath, Gram, Merlock, and Rerir Montes) and four undae (Boreas, Eurus, Notus, and Zephyrus Undae) have been approved for Titan. For details, see the list of Titan feature names in the Gazetteer of Planetary Nomenclature.

  • New Name Approved for a Planitia on Mars

    The name Eridania Planitia has been approved for the Martian feature located at 38S, 238W. For more information, see the database information and the maps of MC-28 and MC-29 in the Gazetteer of Planetary Nomenclature.

  • New Name Approved for Martian Vallis

    The name Havel Vallis has been approved for the Martian vallis located at 1.0N, 302.5E. For more information, see the web page for Havel Vallis and the map of MC-10 in the Gazetteer of Planetary Nomenclature.

  • New Name Approved for Martian Fossae

    The name Sinai Fossae has been approved for the Martian fossae located at 14.0S, 281.0E. For more information, see the gazetteer page for Sinai Fossae and the map of MC-18 in the Gazetteer of Planetary Nomenclature.

  • Names Approved for Two Coronae on Venus

    The names Elihino Corona and Pakoti Corona have been approved for two coronae located in Venus quadrangle V-45. For more information, see the Gazetteer of Planetary Nomenclature.

  • Names Approved for Three Terrae and Two Regions on Titan

    The IAU Working Group for Planetary System Nomenclature has approved names for three terrae (Garotman, Tollan, and Yalaing Terrae) and two regiones (Concordia and Hetpet Regiones) on Titan. For details, see the list of Titan feature names in theGazetteer of Planetary Nomenclature.

  • Names Approved for 36 Features on Lutetia

    Names for 18 craters, 1 dorsum, 2 fossae, 3 labēs, 8 regiones, 2 rimae, and 2 rupēs have been approved on asteroid (21) Lutetia. For more information, see the Lutetia page in the Gazetteer of Planetary Nomenclature.

  • Mercury Feature Coordinates Updated to MESSENGER

    In late 2010, the coordinates of the named features in the Mercury portion of the nomenclature database were updated from values from historical sources to values in the preliminary MESSENGER control network. The purpose of this work was to facilitate the identification of named features on Mercury. Dots representing the coordinates of the centers of named features will fall in the centers of the features when displayed on any map product that was created using the same control network.

    The extents and sizes of the named features were also updated; these data are approximate and are intended solely to give the user sufficient information to identify named features and their rough extents.

    This new set of coordinates was derived using ArcMap version 9.3.1 and the global map of Mercury. Because MESSENGER does not yet have global coverage of Mercury, Mariner 10 data were used to fill in areas where MESSENGER has not yet collected image data. In order for the two data sets to align, the preliminary MESSENGER control network was tied to the Mariner 10 map using several ground truth points.

    The Mercury portion of the Gazetteer of Planetary Nomenclature web site now defaults to showing feature coordinates in the frame of the preliminary MESSENGER control network. The original ‘unknown’ source coordinates are still retained in the gazetteer, but this data set is now considered archival and will not be updated with new names or changes to approved names.

  • Martian Valley System Named Tigre Valles

    The name Tigre Valles has been approved for the Martian valley system located at 12S, 37W. For more information, see the database information and the map of MC-19 in the Gazetteer of Planetary Nomenclature.

  • Martian Craters Named Noord and Resen

    The names Noord and Resen have been approved for two small Martian craters. For more information about these features, or about planetary feature names in general, see the Gazetteer of Planetary Nomenclature.
