| Abstract from DBPedia | The galactic coordinate system is a celestial coordinate system in spherical coordinates, with the Sun as its center, the primary direction aligned with the approximate center of the Milky Way Galaxy, and the fundamental plane parallel to an approximation of the galactic plane but offset to its north. It uses the right-handed convention, meaning that coordinates are positive toward the north and toward the east in the fundamental plane.銀河座標（ぎんがざひょう、galactic coordinate）は天球上の天体の位置を表す天球座標系の一種で、銀河中心と銀河面を基準とする座標系である。 銀河座標では、天球上の緯度と経度にあたるものとして銀緯（ぎんい、galactic latitude: b）と銀経（ぎんけい、galactic longitude: l）を使用する。 (Source: http://dbpedia.org/resource/Galactic_coordinate_system) |
