As of my last update, Saturn is the planet known for its prominent and extensive ring system. However, while Saturn has several rings, it is not specifically noted for having nine continuous rings; the classification of Saturn's rings can vary in number depending on how one defines and counts the individual rings and divisions within them.
If you are referring to another planet or if there have been recent findings about a new type of ring system on a different celestial body, please provide more context or clarify your question!
