How much does Venus planet cost?

Excuse me, but I believe there's a bit of a misunderstanding in your question. The Venus planet, being a celestial body orbiting the Sun within our Solar System, is not a commodity or asset that can be bought or sold. As such, it does not have a monetary value or a cost associated with it. Are you perhaps asking about the value of Venus-related assets in the cryptocurrency or finance world? If so, could you please clarify the specific asset you're referring to?
