Why is Dione important?

Why should we consider Dione as an important celestial body? Is it due to its unique physical characteristics, such as its size, shape, or composition? Or is it because of its strategic location in the Saturnian system, potentially influencing the dynamics and evolution of other moons and even the ring system? Furthermore, does Dione hold any scientific secrets that could provide valuable insights into the formation and evolution of our solar system? As an expert in cryptocurrency and finance, I recognize the potential significance of Dione in other fields, but I'm curious about its significance within the realm of astronomy and planetary science.
