Here's a breakdown:
* Jupiter: YES - It has a prominent ring system, although much fainter than Saturn's.
* Saturn: YES - Known for its spectacular and complex ring system.
* Uranus: YES - It has a faint system of rings, much less visible than Saturn's.
* Neptune: YES - Also has a faint system of rings.
So, the statement is mostly correct, but it excludes Jupiter.
The presence of rings isn't limited to the outer planets:
* Earth: It has a faint dust ring, called the Kordylewski clouds.
Why do these planets have rings?
The prevailing theory is that rings are formed from debris, like dust and ice, left over from the early solar system or from impacts of asteroids or comets.
Here are some key factors:
* Gravity: The planets' strong gravity pulls in this debris.
* Moons: The gravitational influence of moons can also play a role in shaping and maintaining the rings.
* Collisions: The debris particles constantly collide, fragmenting and reforming.
* Distance from the Sun: The outer planets are colder, which allows for more ice to survive in the ring system.
While the presence of rings is a common feature of the outer planets, it's not a universal rule.
