Saturn and its rings are best seen when the planet is at, or near, opposition, the configuration of a planet when it is at an elongation of 180°, and thus appears opposite the Sun in the sky. A Saturnian opposition occurs every year—approximately every 378 days—and results in the planet appearing at its brightest.
The second hypothesis is that the rings were never part of a moon, but are instead left over from the original nebular material from which Saturn formed. [citation needed] A 2007 artist's impression of the aggregates of icy particles that form the 'solid' portions of Saturn's rings. These elongated clumps are continually forming and dispersing.
Fainter planetary rings can form as a result of meteoroid impacts with moons orbiting around the planet or, in the case of Saturn's E-ring, the ejecta of cryovolcanic material. [ 6 ] [ 7 ] Ring systems may form around centaurs when they are tidally disrupted in a close encounter (within 0.4 to 0.8 times the Roche limit ) with a giant planet.
The ring would have formed along the equator due to Earth’s equatorial bulge, similar to how the rings of Saturn, Jupiter, Uranus and Neptune are also around each of those planets’ equatorial ...

2013 and 2017: hexagon color changes. Between 2012 and 2016, the hexagon changed from a mostly blue color to more of a golden color. [21] One hypothesis for this is that sunlight is creating haze as the pole is exposed to sunlight due to the change in season. These changes were observed by the Cassini spacecraft. [21]
Astronomers have long known about the perplexing spokes on Saturn’s rings, which look like apparitions skating along the rings and can be spotted in various locations depending on where the ...
