The close orbit of NASA's Cassini mission, along with advances in technology for Earth-based telescopes, enabled the discovery of the rest. The Sioux Moon Goddess. These moons are thought to be captured asteroids and are among the smallest natural satellites in the solar system. One is a raging volcanic inferno, others create rings around their planets. The largest of these, Triton was discovered by William Lassell in 1846 one day after the discovery of Neptune, it was more than 100 years later before a second moon was found. Dark hydrocarbons falling to the moon long ago, perhaps from the nearby moon Phoebe, may have had more time to absorb more heat, gradually growing and spreading over time. This image reveals mountains only about half that height. [PHOTOS: The Rings and Moons of Saturn]. The equatorial ridge of Iapetus can reach heights of up to 12 miles (20 km). One is a raging volcanic inferno, others create rings around their planets. You tell us.
Another theory suggests that the system originally housed several large moons, similar to Jupiter's Galilean moons, but two fused into Titan. Over the next 200 years, the other seven major satellites were spotted. A large crater on the other side of the moon covers nearly two-fifth of the moon's diameter and is nearly the size of Mimas. William Herschel who discovered Uranus in 1781 also observed the largest two moons, Titania and Oberon, in 1787. Notable Moons – Miranda, Titania, Ariel, Umbriel & Oberon, Other Moons – Cordelia, Ophelia, Bianca, Cressida, Desdemona, Juliet, Portia, Rosalind, Cupid, Belinda, Perdita, Puck, Mab, Francisco, Caliban, Stephano, Trinculo, Sycorax, Margaret, Prospero, Setebos & Ferdinand. They come in a variety of sizes and compositions, from almost pure ice to rocky material, as well as a combination of both. The impact stands out despite the fact that Mimas is one of the most heavily cratered bodies in the solar system, with overlapping impacts covering the surface. The flattened object resembles an elongated potato rather than a sphere, a form that may have been created when an impact demolished a larger moon long ago. Iapetus has a walnut-like shape, with its center bulging outward, and a ridge running around its equator. Other Moons – Nix, Hydra, Kerberos & Styx.
Over the next 200 years, the other seven major satellites were … Scientists think that Saturn's system may have originally housed two such moons, but the second broke up, creating the debris that formed the rings and smaller, inner moons. Astronomers think a collision could have spun the moon on its axis. Enceladus contains more than 100 geysers at its south pole.
But which is the most badass? The smallest and closest orbiting of Saturn's major moons, Mimas cleared the gap known as the Cassini division between two of the planet's rings.
Here's how it will eventually die by fire. NY 10036. A large trench crosses the moon, running diagonally from its north to south pole and spanning three-quarters of the satellite's circumference. The moon has a subsurface ocean that may be friendly to life. Join our Space Forums to keep talking space on the latest missions, night sky and more!
The five largest are Puck, Miranda, Ariel, Umbriel, Titania, and Oberon.

They were discovered in 1877 by astronomer Asaph Hall, who named them for the Latin terms “fear” and “panic”.
The tidally locked moon is heavily cratered not on its leading side but on its back side. The first of Saturn’s moons to be observed was Titan in 1655 by Christiaan Huygens, another moon was not found until 1671 when Giovanni Domenico Cassini discovered Iapetus. Hanwi is the moon spirit in the Sioux mythology. Enceladus is the astrobiology It-Moon of the moment, but can it be beaten in a satellite smackdown?
