Here's the breakdown:

* Outer Planets with Rings:

* Saturn: Known for its spectacular, complex ring system.

* Jupiter: Has a fainter, less prominent ring system.

* Uranus: Has a system of narrow, dark rings.

* Neptune: Also has a faint ring system.

* Outer Planet without Rings:

* Pluto: Pluto, though once considered an outer planet, is now classified as a dwarf planet, and it does not have rings.

So, while most of the outer planets have rings, they are not universally present. The presence of rings is likely related to the planet's gravitational pull and the presence of moons and other debris in its orbital path.
