How much would a planet sell for?

Excuse me, but could you elaborate on the concept of "selling a planet"? As we all know, planets are celestial bodies orbiting stars and are not tangible assets that can be bought or sold in the traditional sense. Are you perhaps referring to some speculative idea of terraforming and colonization, or is there some other, more metaphorical interpretation you have in mind? I'm genuinely curious to understand your question and the context in which you're asking it.
