NASA Confirms Saturns Rings Will Be Gone in 100 Million Years


Context: New NASA research confirms that Saturn is losing its iconic rings at the maximum rate estimated from Voyager 1 & 2 observations made decades ago.

The rings are being pulled into Saturn by gravity as a dusty rain of ice particles under the influence of Saturn’s magnetic field.


Composition and structure:

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 travel through space.

  • Though Saturn appears surrounded by a single, solid ring when viewed by an amateur astronomer, several divisions exist. The rings are named alphabetically in the order of discovery. Thus the main rings are, from farthest from the planet to closest, A, B and C. A gap 2,920 miles wide (4,700 kilometers), known as the Cassini Division, separates the A and B rings.
  • The rings themselves contain a number of gaps and structures. Some are created by Saturn’s many small moons, while others continue to puzzle to astronomers.


Is it only the Saturn to have rings?

Saturn is not the only planet in the solar system to have rings — Jupiter, Uranus and Neptune also contain faint ring systems — but with its satellites spanning three-quarters of the Earth-moon distance (175,000 miles or 282,000 km), it is by far the largest and most visible.
