Each constellation is a first-class knowledge-graph entity resolved through the Scientific Data Engine. Boundaries, areas, and designations follow the International Astronomical Union; stars, deep-sky objects, exoplanets, and meteor showers are the platform's existing, source-backed entities — reused, never duplicated. Unknown values are left blank. See source quality.
