The same gravity that holds galaxies together and keeps planets in their orbits also held you to the Earth on the day you were born.

What colors are Saturn's rings? Recent images from the Cassini spacecraft now orbiting Saturn confirm that different rings have slightly different colors. The above image shows their sometimes-subtle differences in brightness and color. The rings reflect sunlight and so, even if they were perfectly reflecting, would appear the color of the Sun. The ring particles are mostly light water-ice, although these particles can be shaded by an unknown type of darker dirt. Thinner and more isolated rings also naturally appear darker. The brightest section pictured above is Saturn's B ring.
