NASA : The Great Divide .- La gran división

Hola amigos: A VUELO DE UN QUINDE EL BLOG., EN 2.980 millas de ancho (4.800 kilómetros de diámetro) en la división de los anillos de Saturno se cree que es causada po  el satélite  (Luna)  Mimas. Partículas dentro de la órbita de Saturno división casi exactamente dos veces por cada vez que las órbitas de Mimas, que conduce a una acumulación de empujones gravitacionales del satélite(de la luna). Estas interacciones gravitacionales repetidas esculpen el borde exterior del anillo B y mantienen sus partículas pasen a formar parte de la División de Cassini.

Saturn's rings
It's difficult to get a sense of scale when viewing Saturn's rings, but the Cassini Division (seen here between the bright B ring and dimmer A ring) is almost as wide as the planet Mercury. (See PIA11142 for a labeled panorama of features in the rings.)

The 2,980-mile-wide (4,800-kilometer-wide) division in Saturn's rings is thought to be caused by the moon Mimas. Particles within the division orbit Saturn almost exactly twice for every time that Mimas orbits, leading to a build-up of gravitational nudges from the moon. These repeated gravitational interactions sculpt the outer edge of the B ring and keep its particles from drifting into the Cassini Division.

This view looks toward the sunlit side of the rings from about 4 degrees above the ring plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 28, 2016.

The view was acquired at a distance of approximately 740,000 miles (1.2 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 76 degrees. Image scale is 4 miles (7 kilometers) per pixel.

The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.
