Cassini Reveals the Spirals in Saturn's D Ring
Saturn's rings are one of the most iconic features in our solar system. But did you know that each ring has its own name? The innermost ring is called the D Ring, followed by the C Ring, the B Ring, and finally the A Ring. The A Ring is the largest and brightest of Saturn's rings.

Saturn's rings are made up of billions of particles ranging from grains of sand to mountain-size chunks. Composed predominantly of water-ice, the rings also draw in rocky meteoroids as they.

The rings of Saturn are the most extensive ring system of any planet in the Solar System. They consist of countless small particles, ranging in size from micrometers to meters, [1] that orbit around Saturn. The ring particles are made almost entirely of water ice, with a trace component of rocky material.
Saturn's Rings are Back
The Hubble Space Telescope captured a newly revealed image of the mysterious, ghostly shadows on Saturn's rings — the latest sighting of the so-called "spokes" that continue to baffle.
Saturn’s iconic rings are disappearing CNN
Saturn's dynamic D ring January 1, 2007 The Cassini spacecraft has provided the first clear images of the D ring since the Voyager missions. These observations show that the structure of the D ring has undergone significant changes over the last 25 years.
Saturn's Rings Composition, Characteristics & Creation Space
Saturn's D ring is easy to overlook since it's trapped between the brighter C ring and the planet itself. But this dusty ring has plenty to teach us. In this view, all that can be seen of the D ring is the faint and narrow arc as it stretches from top right of the image.
Why does Saturn have rings? NASA Space Place NASA Science for Kids
The D ring is very faint and closest to Saturn. The main rings are A, B and C. The outermost ring, easily seen with Earth-based telescopes, is the A ring. The Cassini Division is the largest gap in the rings and separates the B ring from the A ring. Just outside the A ring is the narrow F ring, shepherded by tiny moons, Pandora and Prometheus.

A brief astronomical history of Saturn's amazing rings
Rings Saturn's rings are thought to be pieces of comets, asteroids, or shattered moons that broke up before they reached the planet, torn apart by Saturn's powerful gravity. They are made of billions of small chunks of ice and rock coated with other materials such as dust.

The E ring is the largest and outermost ring, spanning 621,370 miles (about one million kilometers) and lying next to another faint ring, G. Saturn's F ring is made up of many narrow rings.
Stunning new image of Saturn's rings and several moons captured by JWST •
The D ring spirals, discovered in Cassini images, are believed to be due to a warp in the ring created in the early 1980s. The precise mechanism remains the subject of scientific debate. Over the course of the Cassini mission, scientists have been able to observe the spiral winding ever more tightly as it evolves.

Saturn is encircled by an extensive ring system that, like the rings surrounding Jupiter, Uranus, and Neptune, resides within a region where tides from the parent planet frustrate aggregation of the ring particles into larger bodies ( 1 ). Several 1- to 100-km moons are interspersed within, and along, the peripheries of each of the four systems.
The best pictures of Saturn’s rings The Society
Without realizing it, he'd witnessed a Saturn ring plane crossing. It was not until 1655 that the nature of Saturn's rings began to be understood. In that year, Dutch astronomer Christiaan Huygens proposed that Saturn was surrounded by a solid ring. Improved observations over the next 340 years, most recently by the Voyager 1 and 2 spacecraft.

The rings are about 400,000 kilometers (240,000 miles) wide. That's the distance from the Earth to the Moon! But the rings are as little as 100 meters (330 feet) thick. They range from particles too tiny to see to "particles" the size of a bus. Scientists think they are icy snowballs or ice covered rocks.
