The International Star Registry (ISR) is a for-profit organization founded in 1979 for the purpose of giving the general public the novelty of unofficially naming stars. Products and services are often marketed as gifts or memorials.


The International Astronomical Union (IAU) is the internationally recognized authority which designates stars, planets, asteroids, comets, and other heavenly bodies according to internationally accepted rules. The IAU neither sells naming rights nor does it authorize any other company or organization to do so. The IAU cautions consumers that products and services marketed by other companies have no formal or official validity whatsoever.[1] In fact with a few exceptions of ancient or Arabic names, nearly all stars are designated by catalog numbers rather than names.
