For fun I created an 'Alaskan Name a Star Certificate'. I give them away free at the Marie Drake Planetarium where I volunteer.
With it you can rename a star using a person's name or nickname or with the name of an organization. The name of the person the star is being "renamed" will be recorded in the Marie Drake Planetarium Star Registry (a Star Atlas) next to the star's location.
The certificate includes a space for a real star number and the star's celestial address. The star certificate has the logo of the Marie Drake Planetarium and an Alaskan Flag which is the Big Dipper and the North(ern) or Pole star.
Star certificates are sold as fun novelty gift suitable for any occasion. However, you are not really buying a star. The only organization that can name stars is the International Astronomical Union (IAU) and they don't sell the rights to stars.
