The rings around saturn are caused by a gravitational pull that causes ice and rock masses to orbit the body of the planet.
The rings around uranus are due to not wiping properly.

The ring system of the planet Saturn is obviously wider and brighter than the ring system of Uranus.Aside From that, Saturn's ring system is older, independent from gravitational pull of the moons, and changes angle every 26 years while Uranus's ring system is darker, younger,dependent on "shepherd"moons and stays over the planets equator.

Huge circular basins, marked by low regions surrounded by concentric mountain ranges, decorate the Moon. The giant holes may have formed during a short, violent period from about 3.9 to 3.8 billion years ago. Three hundred to 1000 kilometers in diameter, their sizes suggest that fast-moving objects with diameters of 20 to about 150 kilometers hit the Moon. Numerous smaller craters also formed. If most large lunar craters formed between 3.9 and 3.8 billion years ago, where were the impactors sequestered for over 600 million years after the Moon formed?
One possibility has been studied with computer simulations by Harold Levison and colleagues from the Southwest Research Institute (Boulder, Colorado), Queen's University (Ontario, Canada), and NASA Ames Research Center in California. The idea, originally suggested in 1975 by George Wetherill (Carnegie Institution of Washington), is that a large population of icy objects inhabited the Solar System beyond Saturn. They were in stable orbits around the Sun for several hundred million years until, for some reason, Neptune and Uranus began to form. As the planets grew by capturing the smaller planetesimals, their growing gravitational attraction began to scatter the remaining planetesimals, catapulting millions of them into the inner Solar System. A small fraction of these objects crashed into the Moon and rocky planets, sculpturing the surfaces with immense craters. Calculations suggest that the bombardment would have lasted less than 100 million years, consistent with the ages of craters and impact basins in the lunar highlands.

Saturns rings are comprised mostly of Ice and/or Ice covered rock. The rings around Uranus are comprised mostly of dust.

the reason that those issues weren't observed are a minimum of four. a million. maximum astronomers recognized the planets interior the image voltaic gadget as uninteresting and weren't observing them. very almost all the attempt grew to become into on distant galaxies, neutron stars, quasars, pulsars and so on which had then those days been got here upon. 2. till the form of cost coupled gadgets those issues weren't detectable from Earth. interior the Nineteen Seventies the main important telescopes on earth have been in specific circumstances 30 to 40 years old and trusted chemical photos which curiously isn't mushy adequate. 3. there have been no probes achieving the outer image voltaic gadget till the Nineteen Seventies. 4, there have been no astronomical telescopes of any actual length in orbit.
