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 in 1977. However, Uranus' rings differ from those found surrounding both Jupiter and Saturn. "The outermost epsilon ring is composed mostly of ice boulders several feet across. A very tenuous distribution of fine dust also seems to be spread throughout the ring system." (Hamilton, 2003). In addition, there are several narrow or incomplete rings that surround Uranus. Uranus' rings "are composed of fairly large particles ranging up to 10 meters in diameter in addition to fine dust. Uranus' rings were discovered after Saturn's. The discovery of Uranus' rings "was of considerable importance since we now know that rings are a common feature of planets, not a peculiarity of Saturn alone." (Arnett, 2004).
There are 11 known rings, all very faint; the brightest is known as the Epsilon ring." (Arnett, 2004). By far the largest ring is 1986U2R, which is 2,500 kilometers wide, and approximately 38,000 kilometers from Uranus' center. Ring 6 is 1-3 kilometers wide and approximately 41,840 kilometers from the center of Uranus. Ring 5 is 2-3 kilometers wide and is approximately 42,230 kilometers from the center. Ring 4 is also 2-3 kilometers wide, and is located just past ring 5. Alpha is 7-12 kilometers wide and is 44,720 kilometers from the center. Beta is 7-12 kilometers wide and is 45,670 kilometers from the center. Eta is 0-2 kilometers wide and is 47,190 kilometers from the center. Gamma is 1-4 kilometers wide and is 47,630 kilometers from the center. Delta is 1-4 kilometers wide and is located 48,290 kilometers from the center. 1986U1R is 1-2 kilometers wide and is located 48,290 kilometers from the center. Epsilon, the most visible of the rings from the surface of the Earth, is 20-100 kilometers wide and is located approximately 51,140 kilometers from the center of Uranus. Epsilon is the probably the most visible because it is the outer ring and is much larger than most of the other rings.
Uranus also has shepherd satellites for some of its rings. The moons Cordelia and Ophelia are on either side of Uranus' epsilon ring. In fact, Uranus has a very high number of moons and other satellites. In fact, Uranus has 27 moons, 21 that have been named and six unnamed ones. Unlike the moons of other planets, which have been named after figures in classical mythology, "Uranus' moons take their names from the writings of Shakespeare and Pope." (Arnett, 2004). Most of the moons have circular orbits, although the outer moons have more elliptical orbits.
The moons can also be classified into three groups. The first group is composed of the 5 large moons that were visible from Earth. Two of these large moons, Titania and Oberon, were discovered by Herschel in 1787. In 1851, Lassell discovered two more large moons, Ariel and Umbriel. The most recently discovered large moon was Miranda, which was discovered by Kuiper in 1948.
The next group is composed of 11 small dark inner moons, which were discovered by Voyager 2. These moons were discovered in 1986. These moons are Cordelia, Ophelia, Bianca, Cressida, Desdemona, Juliet, Portia, Rosalind, Belinda, 1986U10, and Puck. These...
With respect to the mythology of the male gods, Zeus, Apollo, and Hephaestus seem to be a combination that matches the dynamism of their female goddess counterparts. These gods represent the good and the bad of males; they also represent the spectrum of power and balance of male energy. There is no one god or goddess myth that I feel fully represents the tension between male and female gods because
Although they are verbal in nature, the striking image of many mnemonics, like MataHari the spy, or a mother delivering nine pizzas makes them effective. Another mnemonic technique is to create a word called an acronym, a word that represents what needs to be remembered (Keeley 1999). Some acronyms, like Radar, or NASA, have become so popular and are used to frequently they have replaced the words they were created

Galileo Galilei played another major role and vastly improved the telescope, allowing future astronomers to make much more accurate calculations because of improved observations. Through his updated telescope, he was able to observe and record the phases of Venus as well as discover several of Jupiter's larger moons. Sir Isaac Newton was another major figure that helped create the ideas of modern astronomy. Through his work in physics, Newton
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
"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. As methane and nitrogen frozen at the poles thaw. As it moves toward its farthest point from
