Why is it free to name a star at Staracle.com while other web sites charge money?
The answer is simple: Nobody owns the stars, therefore nobody should sell them.
Moreover, nobody should sell star names. The only official authority to name stars
is the International Astronomical Union (IAU). And they won't let you name a star.
Therefore, any star naming service you find on the Internet
will simply keep your name in their private database, but it will never be the star's official name.
