Webreference system to replace FK5 J2000. The new system, called the International Celestial Reference System (ICRS), differs profoundly from all predecessors in that the link with solar-system dynamics was broken; the ICRS axes are defined in terms of the directions of a set of extragalactic sources, not in terms of the mean equator and WebThe orientation of the BCRS/ICRS axes also align within 0.02 arcsecond of the Earth's mean equator and equinox for the Fifth Fundamental Catalog (FK5) J2000.0 epoch.
