None of the rocky planets, asteroids, or known Kuiper belt objects have a system of rings. Jupiter, Uranus, and Neptune possess them, but they're all much fainter, sparser, smaller, and less massive than Saturn's. In addition, Saturn's rings are: significantly tilted with respect to the planet's axis of rotation, are made almost exclusively of water-ice, and are actively in the process of evaporating.

Saturn's rings were likely first seen by Galileo in 1610, who could only see a pair of blobs due to the quality of his telescope.
