Final answer:
Every giant planet in our solar system has a ring system; Saturn's rings are the most visible, while Uranus, Neptune, and Jupiter have less prominent ring systems.
Step-by-step explanation:
The question asks about which planet has a ring system. All four of the giant planets in our solar system—Saturn, Jupiter, Uranus, and Neptune—have ring systems made up of various particles ranging from tiny dust grains to larger bodies, all of which orbit around the equator of the planet. Saturn's rings are the most prominent, composed primarily of water ice and easily visible from Earth. Uranus and Neptune also have ring systems, but their rings consist of darker, narrow ribbons with wide gaps in between. Jupiter's ring system is the least conspicuous, mainly composed of dust.
