The water vapor emitted into Saturn's orbit by this activity becomes charged and creates a drag upon Saturn's magnetic field, slowing its rotation slightly relative to the rotation of the planet. [94] [95] [96] An apparent oddity for Saturn is that it does not have any known trojan asteroids.
The current Venusian atmosphere has only ~200 mg/kg H 2 O(g) in its atmosphere and the pressure and temperature regime makes water unstable on its surface. Nevertheless, assuming that early Venus's H 2 O had a ratio between deuterium (heavy hydrogen, 2H) and hydrogen (1H) similar to Earth's Vienna Standard Mean Ocean Water of 1.6×10 −4, [7] the current D/H ratio in the Venusian atmosphere ...
They have the effect of sculpting the rings: giving them sharp edges, and creating gaps between them. Saturn's shepherd moons are Pan , Daphnis , Prometheus (F Ring), Janus (A Ring), and Epimetheus (A Ring). [23] [27] These moons probably formed as a result of accretion of the friable ring material on preexisting denser cores. The cores with ...
The brightness and purity of the water ice in Saturn's rings have also been cited as evidence that the rings are much younger than Saturn, [57] as the infall of meteoric dust would have led to a darkening of the rings. However, new research indicates that the B Ring may be massive enough to have diluted infalling material and thus avoided ...
This is Mimas, the smallest of Saturn's major moons. Other than its giant impact crater, scientists thought Mimas was a rather boring piece of cold rock. Now, a new study says Mimas is much more ...
Currently, cold surface bodies of liquid are found on two worlds in the Solar System, Earth and Saturn's moon Titan. [1] Earth is the only planet with liquid water on its surface. The other "oceans" are found under thick covers of surface ice. If both liquid and frozen water are counted, Earth ranks fifth in volume of its oceans. [2]
Saturn’s moon Enceladus may have all the ingredients necessary to host life, according to a new study based on data from Nasa’s Cassini spacecraft mission.. The spacecraft ended its mission in ...
Thought to have a subsurface ocean maintained by geologic activity, tidal heating, and irradiation. [33] [34] The moon may have more water and oxygen than Earth and an oxygen exosphere. [35] Enceladus: Saturn: Enceladus – potential habitability: Thought to have a subsurface liquid water ocean due to tidal heating [36] or geothermal activity. [37]
