Can you pay to name a planet?

I'm curious, is it actually possible to pay to name a planet? It seems like an intriguing concept, but I'm unsure if it's feasible or if there are any regulations in place that prevent individuals or organizations from doing so. If it is possible, what would be the process for going about it? Would there be any restrictions on what the name could be? And how much would it cost to have a planet named after oneself or a company? I'm eager to learn more about this unique opportunity, if it exists.
