Equatorial ridge. Equatorial ridges are a feature of at least three of Saturn 's moons: the large moon Iapetus and the tiny moons Atlas and Pan. They are ridges that closely follow the moons' equators. They appear to be unique to the Saturnian system, but it is uncertain whether the occurrences are related or a coincidence.
A shepherd moon, also called a herder moon or watcher moon, [citation needed] is a small natural satellite that clears a gap in planetary ring material or keeps particles within a ring contained. The name is a result of their limiting the "herd" of the ring particles as a shepherd. Due to their gravitational influence, shepherd moons deflect ...
Cassini–Huygens ( / kəˈsiːniˈhɔɪɡənz / kə-SEE-nee HOY-gənz ), commonly called Cassini, was a space-research mission by NASA, the European Space Agency (ESA), and the Italian Space Agency (ASI) to send a space probe to study the planet Saturn and its system, including its rings and natural satellites. The Flagship -class robotic ...
Atlas (moon) Atlas is an inner satellite of Saturn which was discovered by Richard Terrile in 1980 from Voyager photos and was designated S/1980 S 28. [5] In 1983 it was officially named after Atlas of Greek mythology, because it "holds the rings on its shoulders" like the Titan Atlas held the sky up above the Earth. [6]
Mimas imaged by the Cassini orbiter, February 2010. Mimas's surface is dominated by craters; the large crater at the right is Herschel. Mimas, also designated Saturn I, is the seventh-largest natural satellite of Saturn. With a mean diameter of 396.4 kilometres or 246.3 miles, Mimas is the smallest astronomical body known to be roughly rounded ...
The rings of Neptune are made of extremely dark material, likely organic compounds processed by radiation, similar to those found in the rings of Uranus. [5] The proportion of dust in the rings (between 20% and 70%) is high, [5] while their optical depth is low to moderate, at less than 0.1. [6] Uniquely, the Adams ring includes five distinct ...
Jupiter is the fifth planet from the Sun and the largest in the Solar System.A gas giant, Jupiter's mass is more than two and a half times that of all the other planets in the Solar System combined and slightly less than one one-thousandth the mass of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm) with an orbital period of 11.86 years.
Saturn Devouring His Son is a painting by Spanish artist Francisco Goya. It is traditionally considered a depiction of the Greek myth of the Titan Cronus, whom the Romans called Saturn, eating one of his children out of fear of a prophecy by Gaea that one of his children would overthrow him. [a] The work is one of the 14 so-called Black ...
