Do you actually buy a star?

Excuse me, but could you elaborate on the concept of purchasing a star? Is this a literal transaction, where one acquires ownership over a celestial body in space? Or is it more of a symbolic gesture, akin to naming a star after someone? I'm genuinely curious about the process and implications of such an unusual purchase. Are there legal frameworks in place to regulate such transactions? And if so, what are the limitations and considerations one should be aware of before making such a purchase? I'm eager to understand the nuances of this fascinating idea.
