  sky   (Site not responding. Last check: 2007-10-09)
The sky is often defined as the place a person sees when he or she looks up from the earth.
The sky is also sometimes defined as the denser gaseous zone of a planet's atmosphere.
Similarly, because the blue hue of the sky during daytime is such a universally observed and understood phenomenon, people say "as sure as the sky is blue" to mean that something is an indisputable fact.

Uranian planets, or ice giants, are a sub-class of gas giants, distinguished from true Jovians by their depletion in hydrogen and helium and a significant composition of rock and ice.
The discovery of a planet-sized satelite of a brown dwarf has blurred the distinction between "planet" and "moon." A brown dwarf, though a star in theory, in practice is often described as in between a planet and a star.
No interstellar planet is known to date, but their existence is considered a likely hypothesis based on computer simulations of the origin and evolution of planetary systems, which often include the ejection of bodies of significant mass.

A planet in common parlance is a large object in orbit around a star that is not a star itself.
Since the term planet has no scientific definition, many astronomers contest that figure, with some saying it should be lowered to eight (removing Pluto from the list), and others claiming it should be raised to fifteen, about twenty, or even dozens, depending on the definition used.
All of the accepted planets in the solar_system are named after Roman gods, except for Uranus, which is named after a Greek god, and the Earth which was not seen as a planet by the ancients (instead considered the centre of the universe).

The concept of the sky, as it is applied here on Earth, can be generalized to mean the space seen when one looks upward from the surface of any planet (see Skies of other planets).
The sky is also sometimes defined as the denser gas eous zone of a planet's atmosphere.
This is an imaginary dome where the sun, star s, planet s, and the moon are seen to be travelling in.

 Planet   (Site not responding. Last check: 2007-10-09)
Planets are thought to form from the collapsing nebula that a planet's star formed out of, aggregating from gas and dust that orbits the protostar in a dense protostellar disk before the star's core ignites and its solar wind blows the remaining material away.
Exceptions include three planets discovered orbiting a burned-out star, or supernova remnant, called a pulsar, comparable in size to the terrestrial planets; and a planet orbiting mu Arae with a mass of approximately 14 times that of the Earth.
No interstellar planet is known to date, but their existence is considered a plausible hypothesis on the grounds that the results of computer simulations of the origin and evolution of planetary systems often include the formation and subsequent ejection of bodies of significant mass.

When Ceres was found orbiting between Mars and Jupiter in 1801, it was initially touted as a planet, but after many smaller objects were found with a similar orbit, it was classified as an asteroid.
Much like "continent", "planet" is a word without a precise definition, with history and culture, playing as much of a role as geology and astrophysics.
Astronomers distinguish between minor planets, such as asteroids, comets, and trans-Neptunian objects; and major (or true) planets.

 Hypothetical Planets   (Site not responding. Last check: 2007-10-09)
In 1901, Gabriel Dallet deduced a hypothetical planet at 47 a.u.
The new planet, later named Pluto, turned out to be disappointingly small, perhaps only one Earth mass but probably only about 1/10 Earth masses or smaller (in 1979, when Pluto's satellite Charon was discovered, the mass of the Pluto-Charon pair turned out to be only about 1/400 Earth mass!).
Anderson concluded that the tenth planet must have a highly elliptical orbit, carrying it far away to be undetectable now but periodically bringing it close enough to leave its disturbing signature on the paths of the outer planets.

 Origins: Are There Other Earth-Like Planets?   (Site not responding. Last check: 2007-10-09)
A rare treat to backyard astronomers who view the skies, the planets in our solar system are especially well studied by astronomers and planetary geologists.
The motions of the planets have been well established for centuries, the chemical abundances in their atmospheres have been analyzed more recently and the changes in their structure, atmospheres and physical appearance have been noted with repeated observations from ground- and space-based observatories.
These planets need to be found at distances from their parent star such that the planet's temperature and atmospheric pressure are supportive of the existence of liquid water.

 Cydonia, Asteroids & Comets & Exploded Planets - Cherubim, Seraphim, Planet Rahab, The Stones of Fire & End ...
The accepted theory for the creation of the asteroid belt is "failed planet accretion" -- that during the primordial beginning of the solar system a planet which astronomers call Astera was forming in the place now occupied by the asteroid belt, but because of its insufficient mass, and due to Jupiter's gravitational influence, it fragmented.
Back in the '50's, when the 200-year-old exploded planet hypothesis was last in vogue, people were working on that, and Ramsey came up with a number of ways in which terrestrial-sized planets could either implode or explode with changes of state of certain elements in the core of terrestrial-sized planets.
Other factions of the rebel angels continued existing with the abilty to travel in the atmosphere outward from earth, space, and amongst the planets - "the stones of fire".

 Sunset at the South Pole   (Site not responding. Last check: 2007-10-09)
When the north pole of a planet is tilted toward the sun, astronomers call it the Summer Solstice; when the south pole is tilted toward the sun it is called the Winter Solstice.
The planet's dense, acidic atmosphere produces a runaway greenhouse effect that keeps the surface at 750 K year-round -- that's hot enough to melt lead.
At the other end of the planet the southern polar cap melts, giving CO back to the atmosphere.

 UA Astrobiologist Helps NASA Search for Life on Other Planets
Her first criterion was the age of a star, because if an older star has planets, they are likely to be older and easier to spot.
She also eliminated stars that have other stars orbiting them, called binary star systems, because in such systems the faint light reflected by planets will be hard for NASA's Terrestrial Planet Finder to see.
To support life, a planet has to be at the right temperature for liquid water to exist on the surface.

 SPACE.com -- 'Super Earth' Discovered at Nearby Star
The other planet, whose existence was confirmed with the help of the new observations, is farther out.
Most of the more than 120 planets found beyond our solar system are gaseous worlds as big or larger than Jupiter, mostly in tight orbits that would not permit a rocky planet to survive.
In a telephone interview, Boss of the Carnegie Institution said the European's analysis of the data represents a "reasonable argument." He said the planet had to form inside the orbit of the larger planet in the system, which orbits the star about twice as far as Earth is from the Sun.

It is the brightest thing in Earth's sky other than the Sun and Moon.
Although this is during the daytime, you may be able to catch the Crescent Moon low in the southern or southeastern sky, with Venus about 3 lunar diameters to the north.
However, there is no Moon in the sky to interfere with observations before dawn, and the radiant in Taurus is well placed, high in the western sky.

- Blue skies are evoked as a symbol for good times, optimism and emotional peace.
- "Blue sky thinking" means coming up with a host of ideas without being restricted to what is practical (similar to brainstorming); in particular, an optimistic assumption is made that there will be no obstacles or opposition to implementation of the ideas.
