Saturn is the planet that most people think of when they think of a giant planet with rings. Other planets have rings, some of which are very faint. Uranus, Jupiter, and Neptune have rings.
Saturn has *rings. And Jupiter has very faint *rings.
Jupiter, Saturn, Uranus, and Neptune have rings, but only Saturn's are easily visible from Earth. Compared to Saturn's prominent disk, the rings of other planets are thin, narrow, and ill-defined.
Several planets have rings, but most of them are pretty faint. The rings of Saturn are different, they are very bright and easy to see with a telescope, and that is why Saturn is called the ringed planet.
There are four planets in our solar system that have ring systems. The most obvious, and dramatic, example is Saturn with it's many complex rings and ring divisions. Jupiter also has a fairly faint ring system, first discovered in 1979. The rings of Uranus are quite well defined, and were the second system of planetary rings discovered in our solar system. Finally, Neptune has a very tenuous set of rings that are mainly small, dark particles of dust.
Yes. The rings of Uranus are composed of material in orbit around the planet.
Jupiter's rings are very faint, dark and narrow. They are mainly comprised of rock and dust, unlike Saturn's rings, which have ice.
There are 13 known rings, all very faint; the brightest is known as the Epsilon ring.
If they were invisible, they wouldn't be rings. The rings of Uranus are dark and faint, and difficult to see even with powerful ground based telescopes, but the do exist. See related link for a full description and photos.
Neptune has five main rings. They are very difficult to see with the naked eye because they are rather faint.
Uranus as well as Neptune (Neptunes' rings are very hard to detect).
Uranus does have dark rings, though they are very faint. They are most likely composed of rocky debris or carbonaceous material.
