Uranus
Uranus was the first planet discovered in contemporary times. It was discovered in 1781 by William Herschel while he was searching the sky with his telescope. It had actually been seen many times before but ignored as simply being another star. "In the beginning Herschel named it "the Georgium Sidus" (the Georgian Planet) in honor King George III of England. Others called it "Herschel." The name "Uranus" was first proposed by Bode in conformity with the other planetary names from classical mythology but didn't come into common use until 1850" (Uranus, 2011).
The only spacecraft to ever visit Uranus was Voyager 2 in 1986. Uranus is different in that most of the planets spin on an axis almost perpendicular to the plane of the ecliptic but Uranus' axis is almost parallel to the ecliptic. At the time of Voyager 2's passage, Uranus' South Pole was pointed almost directly towards the Sun. This results in the odd fact that Uranus' Polar Regions receive more energy input from the Sun than do its equatorial regions. Uranus is nonetheless hotter at...
"Either its axial inclination is a bit over 90 degrees and its rotation is direct, or it's a bit less than 90 degrees and the rotation is retrograde. The issue is that one needs to draw a dividing line somewhere, because in a case like Venus there is little argument that the rotation is indeed not a direct rotation with an inclination of nearly 180 degrees" (Uranus, 2011).
Uranus is the seventh planet from the Sun and the third largest in diameter. It is made up mainly of rock and various ices, with only about fifteen percent hydrogen and very little helium. This is in direct contrast to Jupiter and Saturn which are made up mostly of hydrogen. Uranus and Neptune are in a lot of ways similar to the cores of Jupiter and Saturn less the massive liquid metallic hydrogen envelope. It appears that Uranus does not have a rocky core like Jupiter and Saturn but rather that its material is more or…

Therefore, it is uncertain what causes Uranus' magnetic fields. Furthermore, "Uranus' magnetic field is odd in that it is not centered on the center of the planet and is tilted almost 60 degrees with respect to the axis of rotation. It is probably generated by motion at relatively shallow depths within Uranus." (Arnett, 2004). Like the other gas planets, Uranus has rings." (Arnett, 2004). Nine of Uranus' rings were discovered
Extra-Solar Planets The word planet means "wanderer" in Greek. It derives from the fact that planets within our solar system seem generally to wander eastward about the so-called fixed stars across the zodiac constellations (Kolb). There is no clear consensus precisely defining what constitutes a planet, as distinguished from brown dwarfs, which are the material remnants of burned out ancient stars whose masses where too small to form white dwarfs or
The Moon is believed by many to have been part of the earth and that it was tore off as a result of an initial spin that was too great to hold the planet together. One of the prevailing theories was that involving an impact of large magnitude involving the newly formed Earth and a giant object of the size of Mars hitting Earth and blowing up material that

The events on popular television series like Star Trek or Star Wars are not only plausible, but have scientific merit. That does not make them true, only possible (Kraus, 2007; Cavelos, 2000); 4) Conspiracy theories abound in numerous genres and surrounding numerous events.

"Once every 248 Earth years, Pluto swings inside the orbit of Neptune. It stays there for twenty years. During those twenty years, Pluto is closer to the Sun than Neptune. During this period of time, like the other eight planets, Pluto's atmosphere undergoes a fundamental change in character, briefly developing an atmosphere.
