buy star names or name stars after someone

​

There are organisations in different parts of the world that sell names for the stars in the sky. All you have to do is to go there, fill out the detailed form that they give you, and buy star names or name stars after someone. However, this practice is neither valid nor ethical. These companies are selling fictitious star names. Some stars have traditional Arabic names, but most other stars have just catalogue numbers and positions on the sky. Naming small groups of well-known bodies, like the planets or stars that can be seen by the naked eye, is fine. But there are hundreds of millions of stars. How can all be named? The stars in the sky are for all of us to enjoy, and so they should not be for sale.
