Tethys: Saturn's Icy Moon

Physical characteristics Size comparison of Earththe Moonand Tethys. The crater is now quite flat or more precisely, its floor conforms to Tethys's spherical shape. Cassini's discoveries were the first found in orbit around the ringed planet. At average temperatures of minus degrees C minus degrees Fthe ice on the lunar surface responds much like rock.

Due to the action of tidal and rotational forces, Tethys has the shape of triaxial ellipsoid. Related A Swarm of Ideas. This darkening is responsible for the hemispheric albedo asymmetry mentioned above.

Tethys (moon)

The crater is now quite flat - more precisely, its floor conforms to Tethys's spherical shape. This allows scientists to establish a relative chronology for Tethys. April 14, in Uncategorized Tags: These particles drift in the direction opposite to the rotation of the planet and preferentially impact areas on the leading hemisphere close to the equator.

The latter can be a result of focusing the seismic waves produced by the impact in the center of the opposite hemisphere. The trailing hemisphere gets increasingly red and dark as the anti-apex of motion is approached.

Moons of Saturn

This coloration and darkening of the Tethyan surface is typical for Saturnian middle-sized satellites. The eccentricity of the orbits is shown by the segments extending from the pericenter to apocenter.

Older impact craters are somewhat shallower than young ones implying a degree of relaxation. The most probable candidate is nanophase iron or hematite. We have many great articles about Tethys here at Universe Today.

The cratered terrain is the oldest unit likely dating back to the Solar System formation 4. Giovanni Domenico Cassini Of all the major moons in the solar system, Tethys has the lowest density: This coloration and darkening of the Tethyan surface is typical for Saturnian middle-sized satellites.

A comparable band exists only on Mimas. A comparable band exists only on Mimas. In addition to closely resembling the space station out of Star Wars lore, it boasts the largest valleys in the Solar System and is composed mainly of water ice.

Tethys: Saturn's Icy Moon

A heavily cratered hilly terrain occupies the majority of its surface, while a smaller and smoother plains region lies on the hemisphere opposite to that of Odysseus.

Its origin may be related to a deposition of bright ice particles from the E-ring onto the leading hemispheres and dark particles coming from outer satellites on the trailing hemispheres. Henceforth, the numbering scheme would remain fixed.

The plains have a relatively sharp boundary with the surrounding cratered terrain. The dimensions of this ellipsoid are consistent with it having a homogeneous interior. This is due to the fact that a small part of the surface is covered by smooth plains, which are devoid of the craters and graben that cover much of the planet.

The ocean would have frozen after the moons escaped from the resonance. These particles drift in the direction opposite to the rotation of the planet and preferentially impact areas on the leading hemisphere close to the equator. However, the "Odysseus impact event" could have created some bands of large ice particles seen stretching across the north and south.

The location of this unit near Odysseus' antipode argues for a connection between the crater and plains.Tethys (or Saturn III) is a mid-sized moon of Saturn about 1, km ( mi) across.

Tethys (A Moon of Saturn)

It was discovered by G. D. Cassini in and is named after the titan Tethys of Greek mythology. Tethys has a low density of g/cm 3, the lowest of all the major moons in the Solar System, indicating that it is made of water ice with just a small fraction of lietuvosstumbrai.comciation: /ˈtiːθɪs/ or /ˈtɛθɪs/.

Tethys is Saturn's fifth largest moon. Its irregular shape is miles ( kilometers) in mean radius, with dimensions x x miles ( x x kilometers). This cold, airless and heavily scarred body is very similar to sister moons Dione and Rhea except that Tethys is not as heavily cratered as the other two.

Tethys or Saturn III is a mid-sized moon of Saturn about 1, km ( mi) across. It was discovered by G. D. Cassini in and is named after the titan Tethys of Greek lietuvosstumbrai.com has a low density of g/cm, the lowest of all the major moons in the Solar System, indicating.

Tethys was one of a pair of moons orbiting Saturn that was discovered by Giovanni Cassini in The photo of Saturn's moon Tethys was taken on April 14, and received on Earth April Tethys (or Saturn III) is a mid-sized moon of Saturn about 1, km ( mi) across.
