What planet takes 7 years?

Excuse me, could you elaborate on the phrase "What planet takes 7 years?" Are you referring to a specific astronomical cycle, perhaps the orbital period of a celestial body around a star? If so, which planet are we discussing? Is it a well-known planet in our solar system, or perhaps a hypothetical or extrasolar planet? Could you provide some context or further information to help clarify your question? I'm eager to understand and provide a detailed answer, but I need a bit more information to do so accurately.
