Phrase: Galactic coordinate system | Statement: [Galactic anticenter, usedIn, Galactic coordinate system]

Target entity: Galactic coordinate system
Context triple: [Galactic anticenter, usedIn, Galactic coordinate system]

• A. Geocentric Celestial Reference System
  The Geocentric Celestial Reference System is a relativistic, Earth-centered coordinate framework used in astronomy and space science to precisely describe the positions and motions of celestial objects as observed from Earth.
• B. Gould Belt
  The Gould Belt is a nearby, partial ring of young stars, gas, and star-forming regions tilted to the Milky Way’s plane and encompassing many of the bright constellations visible from Earth.
• C. Galactic anticenter
  The Galactic anticenter is the point in the sky directly opposite the center of the Milky Way, located in the outer region of our galaxy’s disk.
• D. Barycentric Celestial Reference System
  The Barycentric Celestial Reference System is a relativistic, solar-system–centered coordinate framework used in astronomy and astrometry to precisely describe the positions and motions of celestial bodies with respect to the solar system’s center of mass.
• E. Northern Galactic Cap
  The Northern Galactic Cap is a large region of the sky located above the plane of the Milky Way’s disk, commonly targeted by wide-field astronomical surveys for deep imaging and mapping of extragalactic objects.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
