History UsefulNotes / Uranus

Surprisingly, the surface gravity on Uranus is only 0.89 g, which is 11% weaker than Earth despite being larger and more massive. This is in stark contrast to the other gas giants in the Solar System which all have stronger surface gravity than Earth. In fact, the closest planet that Uranus' gravity can be compared to is UsefulNotes/{{Venus}} in this regard, which has 90% Earth's gravity. The reason for the weak surface gravity has to do with the planet's low density.

'''Farnsworth:''' I'm sorry, Fry, but astronomers renamed Uranus in 2620 to end that stupid joke once and for all..\\

[[HehHehYouSaidX Heh heh...]]''[[UranusIsShowing Uranus]]''...

The seventh planet from UsefulNotes/{{the Sun}}, so far away it could be argued that [[{{Pun}} the sun does not shine there.]] It is a "giant planet," and [[{{Gasshole}} full of gases like methane and ammonia]], though its inner composition is various ices and rock which astronomers have said is sort of an icy "pudding" surrounding a solid core. When first encountered, the haziness of the planet at the time made it look like a nearly featureless blue ball; better images over a decade later showed it had striations and white wisp-like clouds. Coincidentally, this fit in with its namesake, the Greek god of the sky.

Another oddity of Uranus is its magnetic field. Unlike Jupiter and Saturn, whose magnetic fields are caused by a layer of metallic hydrogen[[note]]hydrogen that has been compressed to the point that it conducts electricity as a metal would[[/note]], Uranus's magnetic field is produced by a layer of highly compressed water, mixed with ammonia that has condensed and rained down from the upper atmosphere. This appears to be normal for ice giants. The oddity is that Uranus's magnetic field is tilted sixty degrees relative to the planets axis, ''and'' off-center. The reason for this is unknown.

Like all gaseous planets, Uranus experiences differential rotation: different latitudes rotate at different rates. Unlike the other three, Uranus's poles rotate faster than its equator.

Currently, it's on its side in relation to the Sun. This has led to the realization (via observation from the Hubble Space Telescope) that the planet is actually two-toned, with a darker shade of blue on the north half of the planet.

Current models of solar system formation indicate that Uranus began its existence as the outermost of the true planets. It gained its position as the seventh when Neptune and the still hypothetical Planet Nine were vaulted into even more distant orbits.

Uranus has the dubious distinction of being the least important of the four gas giants. Where Jupiter is massive enough to heavily affect the entire rest of the Solar System, Saturn prevented Jupiter from the migrating further inward and destroying the four terrestrial planets, and Neptune governs the Kuiper Belt and created the Scattered Disk, Uranus doesn't really do much besides keep Saturn and Neptune in their current positions -even its climate is ''relatively'' calm next to its two giant neighbors, with rather few atmospheric features to speak of-. Uranus does have the distinction of being the ''coldest'' planet in the Solar System, since unlike Neptune, it has ''no'' internal heat source. Unfortunately, [[https://en.wikipedia.org/wiki/Planet_Nine there is a growing body of evidence that Uranus will lose even that]].

Its most striking feature, however, is that the gas giant is rotating ''on its side'', thanks to being smacked upside its head by [[http://www.scientificamerican.com/article/uranus-axial-tilt-obliquity/ two glancing blows]] from planetoids about the size of JustForFun/{{Earth}} early in its life. Thanks to this orientation, astronomers have joked that the ring system makes Uranus look like [[http://history.nasa.gov/EP-177/ch2-3-3.html it's a bullseye]].

The planet, while visible to the naked eye (albeit very faint), is not one of the classic original planets, and is the first planet to be recognized as one via telescope, thanks to Sir William Herschel, who was originally going [[WesternAnimation/BugsBunny to call the planet]] [[AndCallHimGeorge "George"]], or more specifically, ''Georgium Sidus'' after [[UsefulNotes/TheHouseOfHanover King George III]]. Eventually, Uranus was picked at the suggestion of Johan Elert Bode, keeping in line with the other planets being named after gods from classical mythology. The reasoning was that if the next planet past Jupiter was named for Jupiter's father, than the next planet past Saturn should be named after Saturn's father. [[EarlyInstallmentWeirdness Planet naming conventions being in their infancy at the time]], this left Uranus as the only true planet [[OddNameOut named after a Greek god, rather than the Roman counterpart]]; Uranus is the Romanization of Ouranos, Greek god of the Sky. Because of this break with the theme of the other seven planets, and [[UranusIsShowing other reasons]], some astronomers and enthusiasts have bemoaned that the planet was not named Caelus instead. [[HilariousInHindsight Amusingly]], one of the names that was proposed and rejected was [[UsefulNotes/{{Neptune}} Neptune]].

It has a ring system, like Saturn and other similar planets, a magnetosphere which draws objects into it, and of course [[UsefulNotes/TheMoonsOfUranus moons]].
