“Tethys”的概念、定义、翻译、参考文献-科学参考

Tethys

Astronomy

The fifth-largest satellite of Saturn, average diameter 1062 km, sharing the same orbit as the much smaller moons Calypso and Telesto; also known as Saturn III. Its orbital distance is 294 672 km, and its orbital period 1.888 days, the same as its period of axial rotation. Tethys was discovered in 1684 by G. D. Cassini. It is densely covered with impact craters; one of these, Odysseus, is 445 km across, nearly half the satellite’s diameter. Another prominent feature is Ithaca Chasma, a valley over 1200 km long, up to 100 km wide, and up to 3 km deep. The density of Tethys is 0.97, slightly less than that of water, suggesting that it is composed largely of ice.

Geology and Earth Sciences

One of the major satellites of Saturn, with a radius of 529.9 km; mass 6.22 × 10²⁰ kg; mean density 1000 kg/m³; visual albedo 0.9. It was discovered in 1684 by G. D. Cassini.

Geography

An ocean which developed during Palaeozoic and Mesozoic times, running from the coast of southern Spain to South-East Asia. Great thicknesses of sediment were formed since the sea floor kept subsiding at the same rate as deposits were laid down. These sediments were compacted, subjected to volcanism, and then uplifted and deformed by the earth movements; see Pivnik and Wells (1996) GSA Bull. 108, 10 on the transition from Tethys to the Himalayas, and Schreiber et al. (2011) Geodin. Acta 24, 1, 21 on the subduction of the Alpine Tethys.
