Some astronomical objects have proper names (common names, popular names, traditional names; as opposed to catalogue numbers or other systematic designations).〔〔 This trivially includes the naked-eye planets as well as the Sun and Moon. A small number of stars have proper names in pre-modern astronomical tradition, but most naked-eye stars are identified by their Bayer or Flamsteed designations. In modern astronomy, there has been a tradition of giving proper names to newly discovered heavenly bodies, initiated with the discovery of the planets beyond Saturn, and later extended to minor planets and moons. ==Naming== (詳細はnaming of astronomical objects and surface features in those objects is handled by two bodies of the International Astronomical Union (IAU). The names of major planets, satellites, and surface features in those bodies, are assigned by the Working Group on Planetary System Nomenclature. Names of comets and minor planets are handled by the Committee on Small Body Nomenclature. These bodies are also responsible for the dissemination of the names. The IAU's website has lists of all these names.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Proper names (astronomy)」の詳細全文を読む スポンサード リンク
