Topic: Orthosie (moon)


In the News (Thu 31 Dec 09)

  
  Natural Satellite Encyclopedia Article @ Gazed.org   (Site not responding. Last check: 2007-10-13)
Moons orbiting relatively close to the planet on prograde orbits (regular satellites) are believed to have been formed out of the same collapsing region of protoplanetary disk that gave rise to its primary.
Most regular moons in the solar system are tidally locked to their primaries, meaning that one side of the moon is always turned toward the planet.
In addition to the moons of the various planets there are also over 80 known moons of the dwarf planets, asteroids and other small solar system bodies.

 Orthosie (moon) - Wikipedia, the free encyclopedia
Orthosie (or-thoe'-see-ə, IPA: [ɔrˈθoʊsiə]; Greek = ?), or Jupiter XXXV, is a natural satellite of Jupiter.
Orthosie is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 20,568 Mm in 602.619 days, at an inclination of 142° to the ecliptic (102° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2433.
Orthosie belongs to the Ananke group, retrograde irregular moons which orbit Jupiter between 19.3 and 22.7 Gm, at inclinations of roughly 150°.

 Europa (moon) - Biocrawler   (Site not responding. Last check: 2007-10-13)
The smoothness and markings visible on Europa's surface strongly resemble that of sea ice on Earth, and it is thought that under Europa's surface there is a layer of liquid water kept warm by tidally generated heat.
The temperature on the surface of Europa is 110 K at the equator and only 50 K at the poles, however, so water ice on the moon's surface is as hard as rock.
Of all the moons in the solar system only five others (Io, Callisto, Ganymede, Titan and Triton) are known to have atmospheres.

Most moons are assumed to have been formed out of the same collapsing region of protoplanetary disk that gave rise to its primary.
Several moons are thought to be captured foreign objects, fragments of larger moons shattered by large impacts, or (in the case of Earth's moon) a portion of the planet itself blasted into orbit by a large impact.
Most moons in the solar system are tidally locked to their primaries; an exception is Saturn's moon Hyperion, which rotates chaotically due to a variety of external influences.

Io, innermost of the Galilean satellites and slightly larger that Earth's moon, goes through even greater gravitational flexing, with "tides" of as much as 100 meters (328 feet) in its solid rock surface.
Ganymede is the biggest moon in the solar system and, in fact, is larger than the planets Mercury and Pluto.
Callisto, about the size of Mercury, is the third largest moon in the solar system (Saturn's Titan is #2) and is the outermost of the Galilean satellites.

The Moon is one of the larger natural satellites with a diameter of 2,160 miles.
The moons are 120,000 miles and 131,000 miles from the center of planet Saturn between the moons Mimas and Enceladus.
The smallest moon is Deimos, at Mars, only seven miles in diameter, although its size now is rivaled by the small shepherd moons discovered by Cassini at Saturn and by others yet to be counted and named in the rings around Jupiter, Saturn and other giant gas planets in the outer Solar System.

Moons that are further away from the Sun tend to have more ice than moons that are closer to the Sun.
Our Moon and the moons of Mars have no ice at all (except perhaps in deep craters near the poles), but the moon Europa of Jupiter has a layer of ice that is many kilometers thick.
Moons and planets are formed from numerous large and small fragments that collide with each other and sometimes partially stick together.

The Galilean moons, Io, Europa, Ganymede, and Callisto, have orbital radii of 400,000–2,000,000 km and are among the largest satellites in the Solar System.
It is thought that the three groups of smaller moons may each have a common origin, perhaps as a larger moon or captured body that broke up into the existing moons of each group.
All Jupiter' s moons are tidally locked with the planet so that their rotational periods and orbital periods are the same.

Orthosie (''or-thoe'-see-a'') (Jupiter XXXV) is a natural satellite of Jupiter.
Orthosie is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 20,568 Mm in 602.619 days, at an inclination of 124° to the ecliptic (102° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2433.
In anatomy, the ankle is the part of the lower limb that is located between the foot and the leg, and is actually comprised of two separate joints: the talocrural joint (or "true" ankle joint) and the subtalar joint.

 On This and Other Moons
If the sizes of the moons are expressed relative to their primary (the planet they orbit) there are still more surprises.
Being close to Jupiter (it is the innermost of the Galilean moons) the planet's massive gravity stretches the moon by some 100m and locks its rotation so the same side always faces the planet.
When it was discovered in 1978 it was realised that images previously thought to be of just Pluto had actually represented both the planet and its huge moon, and estimates of the planet's size had to be revised downwards.

Until the discovery of the Galilean moons in 1610, however, there was no opportunity for referring to such objects as a class.
The terms man-made satellite or artificial moon were very quickly abandoned in favor of the simpler satellite, and as a consequence, the term has come to be linked primarily with artificial objects flown in space – including, sometimes, even those which are not in orbit around a planet.
As a consequence of this shift in meaning, the term moon, which had continued to be used in a generic sense in works of popular science and in fiction, has regained respectability and is now used interchangeably with satellite, even in scientific articles.

A natural satellite is a non-artificial object that orbits a planet or other body larger than itself.
Technically, the term could also refer to a planet orbiting a star, or even to a star as it orbits a galactic center; however, these usages are rare, and the term normally applies only to satellites of planets or minor planets.
For example in the case of Earth\'s Moon a portion of the planet itself blasted into orbit by a large impact.

The Lunar and Planetary Institute (LPI) has created a digital version of the Lunar Orbiter Photographic Atlas of the Moon, published in 1971 and considered "the definitive reference manual to the global photographic coverage of the Moon." The site includes all 675 plates contained in the original work, digitally enhanced to increase photo quality.
Visitors can view images by feature name, listed alphabetically or by descending latitude and longitude, or they can search by feature name, photo number, or coordinate range.
Students and general users may wish to consult the even easier to use Consolidated Lunar Atlas, which allows browsing by a long list of plates, thumbnails, or even better, an interactive image map.
