Tethys mid sized moon of saturn discovered

The ocean would have frozen after the moons escaped from the resonance. This darkening is responsible for the hemispheric albedo asymmetry mentioned above. Tethys has two trojan moons, Telesto leading and Calypso trailingand Dione also has two, Helene leading and Polydeuces trailing.

They may have occurred, for instance, during the passage of Tethys through an orbital resonance with Dione or some other moon. 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.

An ancient feature, the crater is nearly flat, with its floor conforming to the shape of the moon. In this case Ithaca Chasma would be the outermost ring graben of Odysseus. They may have occurred, for instance, during the passage of Tethys through an orbital resonance with Dione or some other moon.

Sfn The cooling near-surface layer contracted and the interior expanded.

Temperature maps of Tethys obtained by Cassini have shown this bluish region to be cooler at midday than surrounding areas. The subsurface ocean may have resulted from a 2: As a result, it lacks the heavy cratering of Rhea or Dione, which suggests that it was resurfaced in the recent past.

This is most likely due to the viscous relaxation of the Tethyan icy crust over geologic time. A comparable band exists only on Mimas. It travels around Saturn once every 1. The Italian astronomer spotted both Tethys and Dione on March 21, making them the last two of the four moons first found by the astronomer the other two were Iapetus and Rhea.

The crater is now quite flat - more precisely, its floor conforms to Tethys's spherical shape. The density of Tethys is 0. One of the most interesting explanations proposed is that the rings and inner moons accreted from the ice-rich crust of a much larger, Titan-sized moon before it was swallowed up by Saturn.

Tethys viewed by Cassini 11 April Color patterns Tethys - Red Arcs 11 April The surface of Tethys has a number of large-scale features distinguished by their color and sometimes brightness.

Irregular moons are small satellites with large-radii, inclined, and frequently retrograde orbits, believed to have been acquired by the parent planet through a capture process.
