Saturn's winds and rings
Claim in the list: Winds on Saturn reach about 1,795 km/h, and its rings are only a few dozen meters thick in places.
Verification: Broadly supported, with context. NASA reports atmospheric winds around 1,800 km/h; this is a rounded value close to 1,795 km/h and does not describe every location or atmospheric layer. The main rings are exceptionally thin vertically: a typical figure is about 10 m, with tens of meters reported in some regions or measurement contexts. Some waves and vertical disturbances can extend much farther above the ring plane.
Conclusion: Both are reasonable approximate descriptions: fast winds around 1,800 km/h and typical main-ring vertical thickness around 10 m, with local variation.
