This structure is thought to arise, in several different ways, from the gravitational pull of Saturn's many moons. Some gaps are cleared out by the passage of tiny moonlets such as Pan , [ 48 ] many more of which may yet be discovered, and some ringlets seem to be maintained by the gravitational effects of small shepherd satellites (similar to ...
A study published in the journal Science suggests a hypothetical moon (called Chrysalis) came too close to Saturn's gravitational pull and was torn apart, forming the planet's iconic rings.
According to the IAU's explicit count, there are eight planets in the Solar System; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets, which can be divided further into two gas giants (Jupiter and Saturn) and two ice giants (Uranus and Neptune). When excluding the Sun, the four giant planets account for more than ...
Since, within the Roche limit, tidal forces overwhelm the gravitational forces that might otherwise hold the satellite together, no satellite can gravitationally coalesce out of smaller particles within that limit. Indeed, almost all known planetary rings are located within their Roche limit. (Notable exceptions are Saturn's E-Ring and Phoebe ring.
"Titan's seas are pulled by Saturn's massive gravity, just like our seas, and the tidal range on some of its shorelines may be around a foot (30 cm). Because the tidal period - Titan's day - is ...
The moons of Saturn are numerous and diverse, ... They are probably fragments of larger bodies captured by Saturn's gravitational pull. [30] [31] In 2005, ...
The giant planets (Jupiter, Saturn, Uranus, and Neptune) ... thanks to its gravitational pull causing a slight but detectable variation in the orbit of Uranus. [294]
18 May 2004 – Cassini entered the Saturn system. The gravitational pull of Saturn began to overtake the influence of the Sun. 20 May 2004 – The first picture of Titan with better resolution than any Earth-based observation was released. It was taken 5 May from a distance of 29.3 million kilometers (18.2 million miles).
