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.

the planet?Pluto is the farthest planet from the Sun (usually) and by far the smallest. Pluto is smaller than seven of the solar system's moons (the Moon, Io, Europa, Ganymede, Callisto, Titan and Triton). \n\n        orbit:    5,913,520,000 km (39.5 AU) from the Sun (average)\n        diameter: 2274 km\n        mass:     1.27e22 kg\nIn Roman mythology, Pluto (Greek: Hades) is the god of the underworld. The planet received this name (after many other suggestions) perhaps because it's so far from the Sun that it is in perpetual darkness and perhaps because "PL" are the initials of Percival Lowell. \nPluto was discovered in 1930 by a fortunate accident. Calculations which later turned out to be in error had predicted a planet beyond Neptune, based on the motions of Uranus and Neptune. Not knowing of the error, Clyde W. Tombaugh at Lowell Observatory in Arizona did a very careful sky survey which turned up Pluto anyway. \nAfter the discovery of Pluto, it was quickly determined that Pluto was too small to account for the discrepancies in the orbits of the other planets. The search for Planet X continued but nothing was found. Nor is it likely that it ever will be: the discrepancies vanish if the mass of Neptune determined from the Voyager 2 encounter with Neptune is used. There is no Planet X. But that doesn't mean there aren't other objects out there, only that there isn't a relatively large and close one like Planet X was assumed to be. In fact, we now know that there are a very large number of smaller objects in the Kuiper Belt beyond the orbit of Neptune. \nPluto is the only planet that has not been visited by a spacecraft. Even the Hubble Space Telescope can resolve only the largest features on its surface (left and above). A spacecraft called New Horizons was launched in January 2006. If all goes well it should reach Pluto in 2015. \nFortunately, Pluto has a satellite, Charon. By good fortune, Charon was discovered (in 1978) just before its orbital plane moved edge-on toward the inner solar system. It was therefore possible to observe many transits of Pluto over Charon and vice versa. By carefully calculating which portions of which body would be covered at what times, and watching brightness curves, astronomers were able to construct a rough map of light and dark areas on both bodies. \nIn late 2005, a team using the Hubble Space Telescope discovered two additional tiny moons orbiting Pluto. Provisionally designated S/2005 P1 and S/2005 P2, they will be assigned real names when the discovery is confirmed. They are estimated to be between 60 and 200 kilometers in diameter. \nPluto's radius is not well known. JPL's value of 1137 is given with an error of +/-8, almost one percent. \nThough the sum of the masses of Pluto and Charon is known pretty well (it can be determined from careful measurements of the period and radius of Charon's orbit and basic physics) the individual masses of Pluto and Charon are difficult to determine because that requires determining their mutual motions around the center of mass of the system which requires much finer measurements -- they're so small and far away that even HST has difficulty. The ratio of their masses is probably somewhere between 0.084 and 0.157; more observations are underway but we won't get really accurate data until a spacecraft is sent. \nPluto is the second most contrasty body in the Solar System (after Iapetus). \nThere are some who think Pluto would be better classified as a large asteroid or comet rather than as a planet. Some consider it to be one of the larger Kuiper Belt objects (also known as Trans-Neptunian Objects). There is considerable merit to the latter position, but historically Pluto has been classified as a planet and it is very likely to remain so. Further complicating the situation, one such object (2003UB313) was recently discovered that is almost certainly larger than Pluto. Should it, too, be classified as

Ceres is the most massive asteroid: it contains more than 30% of the total mass of all asteroids taken together.\n\nIt is also the largest asteroid and the first to be discovered on January 1, 1801 (easy to remember).

Uranus, 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\nGo to the site below.  It has all kinds of info, even on all of the moons.  I hope this helps :)

First of all, Charon (Pluto's moon) is not bigger than Pluto.\nPluto has a diameter of about 2274 km and a mass of about 1.27 E22 kg.\nCharon has a diameter of about 1212 and a mass of about 1.90 E21 kg.\n\nBut even if a moon is larger than another celestial body, it should not automatically be bumped up to "planet status".\nAfter all, our moon ("the moon") is larger than pluto, but it is not a planet.

the object 2003 UB313, unofficially known as xena, is about 5 percent larger than pluto, but many favor the reclassification of the bodies in the solar system into three groups, the rocky terrestrials, the gas giants, and the ice dwarfs.  there are hundreds of small icy bodies orbiting the sun more distant than neptune i.e. pluto, quaoar, sedna, and 2003 UB313.

Jupiter has four large moons and dozens of smaller ones (there are about 60 known moons so far). Galileo first discovered the four largest moons of Jupiter, Io, Europa, Ganymede, and Callisto in 1610, using a 20-power telescope; these moons are known as the Galilean moons. \n\nThe moons of Jupiter are (in order by their distance from Jupiter): Metis, Adrastea, Amalthea, Thebe, Io, Europa, Ganymede (the biggest), Callisto (the second biggest), Leda (the smallest), Himalia, Lysithea, Elara, Ananke, Carme, Pasiphae, Sinope, and many newly-discovered moons that haven't been named yet.

Largest known to date is the "puffy planet" HAT-P-1b orbiting the sunlike star ADS 16402 B, one of a binary pair of G0 V stars 450 light yeard away, in the constellation Lacerta. Our sun is of spectral class G2 V i.e. a little cooler than ADS 16402 B.\n\nHAT-P-1b has a radius of 1.36 x the radius of Jupiter. \n\nIt was discovered on 13 September 2006 and is 450 light years away. It has the lowest density of any known extrasolar planet. It also has the name Krais.\n\nIt was announced as follows:\n\n"Using small automated telescopes in Arizona and Hawaii, the HATNet project has detected an object transiting one member of the double star system ADS 16402 AB. This system is a pair of G0 main-sequence stars with age about 3 billion years, at a distance of ~139 parsecs and projected separation of ~1550 AU. The transit signal has a period of 4.46529 days."\n\nNote: Only the radii of transiting planets are known.

Mercury, Venus, Mars, Jupiter, and Saturn were all known in ancient times.  They are named after Roman mythological figures (other societies had different names for them, but the Roman names are what we use in the West).  Uranus (1700s), Neptune (1800s), and Pluto (1930) were discovered after the invention of the telescope, but the tradition of Roman Gods was continued by the discoverers.  The only discoverer's name I can remember is the famous astronomer William Herschel, who discovered Uranus.  I'm sure you can find out the names of Neptune's and Pluto's discoverers with a Google search.
