The term "Kappa2 Coronae Australis" is not a widely recognized astronomical designation and does not appear in standard modern celestial catalogs, such as the Yale Bright Star Catalogue, the Hipparcos Catalogue, or the Henry Draper Catalogue.
While the constellation Corona Australis (the Southern Crown) contains a star system designated Kappa Coronae Australis (κ CrA, also known as HD 170873), this system is typically treated as a single Bayer designation. Unlike other stars where multiple components visible to the naked eye are distinguished by numerical superscripts (e.g., Alpha1 and Alpha2 Capricorni), Kappa Coronae Australis is not standardly divided into "Kappa1" and "Kappa2" in scientific literature.
Kappa Coronae Australis itself is a spectroscopic binary star system located approximately 490 light-years from Earth, featuring a primary star of spectral type B9V. It is possible that "Kappa2 Coronae Australis" refers to a specific component of this system or a nearby faint star in a non-standard or historical local catalog; however, there is insufficient evidence in contemporary astronomical databases to confirm such a designation as an established entity.
