maybe you wanted to write 10th planet, not 11th planet.\n\nmaybe there was such a thing but i don't see any records of it on nasa-s site.\n\nWhat i do see is the report of the 10-th planet being discovered, maybe that's what u  were reffering to.\n\nhere's the link\n\nhttp://science.nasa.gov/headlines/y2005/29jul_planetx.htm

Uranus is the seventh planet from the Sun and the third largest (by diameter). Uranus is larger in diameter but smaller in mass than Neptune. \n\n        orbit:    2,870,990,000 km (19.218 AU) from Sun\n        diameter: 51,118 km (equatorial)\n        mass:     8.683e25 kg\n\n\nHardcopy The New Solar System \nSummarizes what we've learned from interplanetary explorations in the last 25 years. My primary reference for The Nine Planets. \n\nThe Compact NASA Atlas of the Solar System \nThis 'road map' of the solar system is the definitive guide for planetary science. \n\nThe Tempest \nby William Shakespeare \n\nThe Rape of the Lock \nby Alexander Pope \nCareful pronunciation may be necessary to avoid embarrassment; say "YOOR a nus" , not "your anus" or "urine us". \n\nUranus is the ancient Greek deity of the Heavens, the earliest supreme god. Uranus was the son and mate of Gaia the father of Cronus (Saturn) and of the Cyclopes and Titans (predecessors of the Olympian gods). \n\nUranus, the first planet discovered in modern times, was discovered by William Herschel while systematically searching the sky with his telescope on March 13, 1781. It had actually been seen many times before but ignored as simply another star (the earliest recorded sighting was in 1690 when John Flamsteed cataloged it as 34 Tauri). Herschel named it "the Georgium Sidus" (the Georgian Planet) in honor of his patron, the infamous (to Americans) 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. \n\nUranus has been visited by only one spacecraft, Voyager 2 on Jan 24 1986. \n\n Most of the planets spin on an axis nearly 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 at 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 nevertheless hotter at its equator than at its poles. The mechanism underlying this is unknown. \n\nActually, there's an ongoing battle over which of Uranus' poles is its north pole! 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 problem is that you need to draw a dividing line *somewhere*, because in a case like Venus there is little dispute that the rotation is indeed retrograde (not a direct rotation with an inclination of nearly 180). \n\nUranus is composed primarily of rock and various ices, with only about 15% hydrogen and a little helium (in contrast to Jupiter and Saturn which are mostly hydrogen). Uranus (and Neptune) are in many ways similar to the cores of Jupiter and Saturn minus 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 less uniformly distributed. \n\nUranus' atmosphere is about 83% hydrogen, 15% helium and 2% methane. \n\n Like the other gas planets, Uranus has bands of clouds that blow around  rapidly. But they are extremely faint, visible only with radical image enhancement of the Voyager 2 pictures (right). Recent observations with HST (left) show larger and more pronounced streaks. Further HST observations show even more activity. Uranus is no longer the bland boring planet that Voyager saw! It now seems clear that the differences are due to seasonal effects since the Sun is now at a lower Uranian latitude which may cause more pronounced day/night weather effects. By 2007 the Sun will be directly over Uranus's equator. \n\nUranus' blue color is the result of absorption of red light by methane in the upper a

New planet, discovered by the Samuel Oschin Telescope at the Palomar Observatory near San Diego, Calif., on Jan. 8, 2005,  is yet to be formally named.\n\n(This  newly-discovered object is more distant than the mysterious planetoid SEDNA discovered in 2003. Sedna is designated 2003 VB12.)\n\n Is at least as big as Pluto and about three times farther away from the Sun than Pluto. It is very cold and dark.It is currently about 97 times farther from the sun than Earth, or 97 Astronomical Units (AU). For comparison, Pluto is 40 AU from the sun. \n\nThis places the new planet more or less in the Kuiper Belt, a dark realm beyond Neptune where thousands of small icy bodies orbit the sun. The planet appears to be typical of Kuiper Belt objects--only much bigger. Its sheer size in relation to the nine known planets means that it can only be classified as a planet itself

kooolcha is right, the first forms of life on Earth were most likely bacteria.  They were probably prokaryotic cells (eukaryotes are thought to have evolved from several prokaryotes joining together, organelles are thought to be evidence of this) that lacked internal structures, including the nucleus.

The earliest living organisms were single-celled. They were prokaryotes, probably bacteria or archaea. They lived 3.8 billion years ago in the Eoarchean Era, a subdivision of the Archean Era.

Uranus was the first planet to be discovered that was not known in ancient times; although it had been observed on many previous occasions, it was always mistakenly identified as a star. The earliest recorded sighting was in 1690 when John Flamsteed catalogued it as 34 Tauri. Flamsteed observed Uranus twice again. Sir William Herschel formally discovered the planet on March 13, 1781, but reported it on April 26, 1781, as a "comet."\n\nHerschel originally named it Georgium Sidus (George's Star) in honour of King George III of Great Britain. When it was pointed out that sidus means star and not planet, he rebaptised it the Georgian Planet. This name was not acceptable outside of Britain. Lalande proposed in 1784 to name it Herschel, at the same time that he created the planet's symbol ("a globe surmounted by your initial"); his proposal was readily adopted by French astronomers. Prosperin, of Uppsala, proposed the names Astraea, Cybele, and Neptune (now borne by two asteroids and a planet). Lexell, of St. Petersburg, compromised with George III's Neptune and Great-Britain's Neptune. Bernoulli, from Berlin, suggested Hypercronius and Transaturnis. Lichtenberg, from Göttingen, chimed in with Austräa, a goddess mentioned by Ovid (but who is traditionally associated with Virgo). The name Minerva was also proposed. Finally, Bode, as editor of the Berliner Astronomisches Jahrbuch, opted for Uranus, after Latinized version of the Greek god of the sky, Ouranos; Maximilian Hell followed suit by using it in the first ephemeris, published in Vienna. Examination of earliest issues of Monthly Notices of the Royal Astronomical Society from 1827 shows that the name Uranus was already the most common name used even by British astronomers by then, and probably earlier. The name Georgium Sidus or "the Georgian" were still used infrequently (by the British alone) thereafter. The final holdout was HM Nautical Almanac Office, which did not switch to Uranus until 1850.\n\nIn the Chinese, Japanese, Korean, and Vietnamese languages, the planet's name is literally translated as the sky king star (天王星).\n\nHope that's not too long for you!!\n\nP.S. I don't believe your claim that a professor wants a paper on a Saturday. I think you're curious, and impatient, and wanted to know sooner rather than later. It's OK to be curious as long as you own up to it. I'm not saying I'm sure you were lying, but I've got a hunch. Just don't be self-conscious about wanting information.

no there is no 10th planet.\n\nwell scientists argue that pluto is small and should not be called a planet.\n\nso when they discovered Sedna( the 10th planet), it was smaller than pluto and so was considered as a mini planet.

Earth is the third planet from the Sun. It is the largest of the solar system's terrestrial planets, and the only planetary body that modern science confirms as harboring life. Scientific evidence indicates that the planet formed around 4.57 billion (4.57×109) years ago, and shortly thereafter (4.533 billion years ago) acquired its single natural satellite, the Moon.

The first of the planets to be "discovered" was named after the muse of Astronomy (Urania). Uranus is also the name of Saturn's father. Uranus was discovered by William Herschel in 1781, though it had been mistakenly mapped in the past as a star. It is possible under the correct conditions to see Uranus with your just eye (no telescope), though it is pretty difficult to do, and you would need to have good eyesight and know exactly where to look to see it. Of course, you have to pronounce the name correctly. If you say something that sounds like "yer-anus," I don't think you'll make too many friends that way, unless they are proctologists. You should instead say the name as "yer-ah-nis" - not much of an improvement, but it may help.\n\nUranus is so far away that we can't get a great deal of information on it from this distance. A few things we can see are its tilt and rotation rate. Uranus is pretty much tipped over on its side. You know that the Earth is tilted over 23 1/2 degrees; Uranus is tilted over 98 degrees! This means it is on its side (since being 90 degrees would be exactly on its side). Due to this the seasons on Uranus are pretty extreme, especially if you are located at one of the poles. It takes Uranus about 84 years to go around the Sun, so the seasons last for about 21 years. If you were located at one of the poles, you would have 21 years of constant daylight during summer and 21 years of continual darkness during the winter. The temperatures would be pretty extreme. Not only is the planet tilted over, but the  rings and satellites are also in tilted orbits about Uranus. It is likely that early in its history the planet was knocked over by an impact and as the system formed (as the satellites and rings formed), they also ended up in tilted orientations.\n\n Figure 1. The orbit and tilt of Uranus are shown. Uranus is tilted pretty much on its side, so there are times when only certain parts of it will get any sunlight. This is especially true for the polar regions. \n\nThere are several very thin rings around Uranus. The rings were discovered from the Earth by accident in 1977. Astronomers were trying to study the atmosphere of the planet by watching how the light of a star would change (get absorbed by the atmosphere) as the planet moved in front of it. Before the star was anywhere close to the planet, the star's brightness faded several times. This happened again when the star was located on the other side of the planet. Now it is possible that the star could have been eclipsed by some moons, but that would have required some very precise alignments of the moons with the distant star. Rings were the cause for the dimming of the starlight! The rings are rather similar to Jupiter's ring in that they are made of darker material as well as small microscopic particles - stuff like dust. Uranus actually has 11 main rings, far fewer than Saturn.\n\n Figure 2. The dimming of a star's light as it approached Uranus indicated that there are rings around Uranus. \n\nViewing Uranus from the Earth doesn't provide much information, so let's send a spacecraft out there. Actually, we have - the only spacecraft to visit Uranus was Voyager 2 in January of 1986. The other Voyager spacecraft did not visit any other planets after its encounter with Saturn, while Voyager 2 continued on to Uranus and Neptune. All of the up close images we have of them are from that one spacecraft. What did it see?\n\nWhen Voyager 2 flew by Uranus, there were no cloud features (spots) as had been seen on Jupiter and Saturn. In fact, there are no markings at all; the atmosphere of Uranus appeared to be very dull. This was really surprising, since at the time that the Voyager spacecraft flew by Uranus, one of the poles was pointed toward the Sun. Astronomers thought that this would have caused the atmosphere to heat up a great deal and therefore produce a bunch of storms. It was a bit co

There are 6 planets that even the ancients knew about.  From the sun outward, they are Mercury, Venus, Earth, Mars, Jupiter, and Saturn.  (of  course, the ancients did not know that Earth was quite a bit like those little points of light that moved through the heavens).  William Herschel discovered Uranus in 1781. Neptune was discovered on September 23, 1846 by Johann Gottfried Galle. And Clyde Tombaugh discovered Pluto on February 18th, 1930.\n\nA few other discoveries may turn out to be planets.  In 2003 Mike Brown and two other astronomers discovered an object larger than Pluto, temporarily named 2003 UB313.  The International Astronomical Union will make a determination whether UB313 will be called a planet, and they'll also give it a proper name from mythology.  \n\nAnd astronomers have found other planet-sized bodies circling distant stars. As of May 18th, 193 of these "extra-solar" (meaning away from our sun) planets have been discovered.  See the exoplanet link below for more info.\n\nSo, to sum things up, from the sun outward, your list is:\n\nMercury\nVenus\nEarth\nMars\nJupiter\nSaturn\nUranus\nNeptune\nPluto\nUB 313 (maybe)\n\nand 193 planets somewhere else in our Milky Way galaxy.
