Multi-ringed impact basin Valhalla on Jupiter's moon Callisto ( moon ) | Callisto

The comet had apparently passed extremely close to Jupiter on July 7, 1992, just over above the planet's cloud topsa smaller distance than Jupiter's radius of, and well within the orbit of Jupiter's innermost moon Metis and the planet's Roche limit, inside which tidal forces are strong enough to disrupt a body held together only by gravity.

The subsurface water ocean of Jupiter's moon Europa may harbor life, especially at hypothesized hydrothermal vents at the ocean floor.

For example, the revolution period of Jupiter's moon Io is 152853. 5047 seconds, a value that would be represented in standard-form scientific notation as 1. 528535047 seconds.

Galileo captures a dynamic eruption at Tvashtar Catena, a chain of volcanic bowls on Jupiter's moon Io.

* 1998 – Data sent from the Galileo spacecraft indicates that Jupiter's moon Europa has a liquid ocean under a thick crust of ice.

Jupiter's moon Ganymede has a small magnetosphere, but it is situated entirely within the magnetosphere of Jupiter, leading to complex interactions.

* Metis ( moon ), the innermost of Jupiter's known moons

Over a period of several months, Jean Picard and Rømer observed about 140 eclipses of Jupiter's moon Io, while in Paris Giovanni Domenico Cassini observed the same eclipses.

* 2001 – NASA's Galileo spacecraft passes within 112 miles of Jupiter's moon Io.

The distinctive colors of Jupiter's volcanic moon Io are attributed to various forms of molten, solid and gaseous sulfur.

On Earth, just as upon Jupiter's moon Io, elemental sulfur occurs naturally in volcanic emissions, including emissions from hydrothermal vents.

One example of this is Jupiter's ice-covered moon Europa, where a MeV sulfur ion from Jupiter's magnetosphere can eject up to 10, 000 H < sub > 2 </ sub > O molecules.

Tidal heating produces dramatic volcanic effects on Jupiter's moon Io.

A crater, Valhalla, located on the planet Jupiter's moon Callisto, is named after the hall.

** Data sent from the Galileo probe indicates that Jupiter's moon Europa has a liquid ocean under a thick crust of ice.

* 5. 262 Mm — Diameter of Jupiter's moon Ganymede, the largest moon in the solar system

* Possible manned mission by NASA to Jupiter's moon, Callisto.

The NASA / MSFC Human Outer Planets Exploration ( HOPE ) group has investigated a manned MTF propulsion spacecraft capable of delivering a 163 933-kilogram payload to Jupiter's moon Callisto using 106-165 metric tons of propellant ( hydrogen plus either D-T or D-He3 fusion fuel ) in 249 – 330 days.

The University of Illinois has defined a 500-tonne " Fusion Ship II " concept capable of delivering a 100, 000kg manned payload to Jupiter's moon Europa in 210 days.

Metis lies inside Jupiter's synchronous orbit radius ( as does Adrastea ), and as a result, tidal forces slowly cause its orbit to decay, and the moon will eventually impact Jupiter.

Several of Jupiter's small innermost moons, namely Metis and Adrastea, are within Jupiter's ring system and are also within Jupiter's Roche limit.

Metis is the innermost of Jupiter's four small inner moons.

* Orange ( Jupiter's moons ): Callisto, Ganymede, Io, Europa, Amalthea, Himalia, Elara, Thebe, Metis, Adrastea, Sinope.

For example, Jupiter's moon Himalia, Saturn's moon Phoebe, and Neptune's moon Nereid have rotation periods in the range of ten hours, while their orbital periods are hundreds of days.

Comparison of size of the Kuiper belt ( large faint torus ) with the star VY Canis Majoris ( within Saturn's orbit ), Betelgeuse ( inside Jupiter's orbit ) and R Doradus ( small central red sphere ) together with the orbits of Neptune and Uranus, to scale.

Pound's observations with it of the five known satellites of Saturn enabled Halley to correct their movements ; and Newton employed, in the third edition of the Principia, his micrometrical measures of Jupiter's disc, of Saturn's disc and ring, and of the elongations of their satellites ; and obtained from him data for correcting the places of the comet of 1680.

Jupiter's moon Europa and Saturn's moon Enceladus may also harbor lakes or oceans below a thick crust of ice.

For example, Saturn's Enceladus and Jupiter's Io have enough tidal heating to liquify its inner core, even if a moon is not conductive to support a dynamo.

More generally, clouds, the ocean, Saturn's bands, Jupiter's Red Spot, and the sun's corona show this instability.

The planet Venus and Jupiter's moon Europa have numerous lineae ; Saturn's moon Rhea has several.

Both Jupiter's moon Ganymede and Saturn's moon Titan are larger than Mercury, and Titan even has a substantial atmosphere, thicker than the Earth's.

Another aspect common to the gas giants is their many natural satellites, two of which are larger than the planet Mercury ( Jupiter's Ganymede and Saturn's Titan ).

Saturn's astrological symbol is combined with that of Jupiter's to create the Symbol of Jusa, an icon created by Cantodea that reflects her spirituality and has become an insignia for herself and her music.

He was also the great-great-grandson of famous Italian-French astronomer, Giovanni Domenico Cassini, discoverer of Jupiter's Great Red Spot and the Cassini division in Saturn's rings.

In addition to Earth-based observations, diapirism is thought to occur on Neptune's moon Triton, Jupiter's moon Europa, Saturn's moon Enceladus, and Uranus's moon Miranda.

Like Jupiter's magnetic field, Saturn's is created by a fluid dynamo within a layer of circulating liquid metallic hydrogen in its outer core.

The processes driving Saturn's magnetosphere are similar to those driving Earth's and Jupiter's.

Just as Jupiter's magnetosphere is dominated by plasma co – rotation and mass – loading from Io, so Saturn's magnetosphere is dominated by plasma co – rotation and mass – loading from Enceladus.

Unlike Jupiter's, the Saturn's main auroral ovals are not related to the breakdown of the co – rotation of the plasma in the outer parts of the planet's magnetosphere.
