Uranus is the seventh planet (counted from the Sun) in the Solar System. It's a gas giant *snicker* like Jupiter, Saturn and Neptune. It is one of the two major planets discovered in modern times, as all of the rest are bright enough to have been known since ancient times. (The other is Neptune. And Pluto is not a planet.)
Uranus is named after the Roman spelling/adaptation of Ouranos, the primordial Greek god/personification of
arses the sky; as part of the interminable wars among the generations of Greek gods (before his grandson Zeus/Jupiter and his fellow Olympians put a stop to it, at any rate), he had his testicles cut off. By his own son (yes, Zeus' dad). Tough breaks. The planet is about 19 times larger than Earth, and 20 times more fun to say when you say it the way Americans for some reason generally do. The name has been the target of an immature joke ever since it was discovered and named in the 1780s. According to some stuffy twerps, the planet's name is not pronounced the way the joke requires. It is actually pronounced more along the lines of "yoo-ruh-nuss" or "yur-uh-nuss," not "yer anus." Unfortunately that runs into urinous, and Webster's doesn't agree, both pronunciations are correct. Can't win. Some people take to pronouncing it, "yoo-ran-us" to avoid getting snickered at. Maybe you can win, after all! Why this whole issue wasn't avoided by naming the planet Caelus after the Roman god of the sky is a mystery for the ages. Maybe it's got something to do with the person discovering it being well read on ancient mythology but no native speaker of English, let alone a snickering fifteen year old schoolboy.

Uranus has an axial tilt of almost 90 degrees making its axis almost parallel to the plane of the ecliptic. It also has rings, 27 moons, and a magnetic field that is not centered and is tilted at an angle to the axis of rotation. Fun fact: unlike the moons of all other planets (save Earth, of course), the moons of Uranus are not named after mythological figures, but rather after characters from the plays of William Shakespeare and from Alexander Pope's mock-epic poem The Rape of the Lock. This is because as the first planet to be discovered after the invention of a telescope, since it was discovered by someone living in England, it was deemed appropriate to name its moons after figures from prestigious works of British literature, in recognition of its discoverer's nationality.
Uranus was actually discovered several decades before it was discovered. In 1690, John Flamsteed was cataloging all the faint naked-eye stars, and called Uranus "34 Tauri." It wasn't until 1781 that William Herschel (born in Hannover and thus not a native English speaker) realized this "star" was in fact moving. He initally wanted to name it after King George III -- the same guy America had declared independence from some years earlier -- but let's face it, "Planet George" is a stupid name (which is why it was never suggested) and Giorgium Sidus ("The Georgian Star", which is what Herschel actually proposed) is at least as stupid. It was Johann Elert Bode (not a native speaker of English either) who suggested Uranus, to preserve the mythological theme of the other planets. Bode's reasoning was that if Jupiter was the father of Mars, and Saturn was the father of Jupiter, then the next planet in line should be the father of Saturn. Unfortunately, he missed the mark a bit by Romanizing the Greek name rather than using the actual Roman name, and Uranus stuck.
Later observations of Uranus's motion indicated that an eighth unseen planet was tugging on it. This planet was eventually discovered, in precisely the position predicted by these calculations, and was named Neptune.
Fundamentalist Christian quote
“”Guess what happens when you find a planet? You get to name it! Well, Herschel was not ancient Roman who believed in false gods. In fact, he was a devout Christian. Because of this, he didn't want to name Uranus after a Roman god. Instead, he wanted to name Uranus after his king, King George III. Not everyone loved King George, however, so many people wanted Herschel to name Uranus after himself, calling it planet Herschel. In the end, they decided to keep with tradition and name Uranus after another Roman god. It is such a shame that the planets in God's wonderful creation, which were made for His glory, have been named after Satan’s counterfeit gods. One day, when we are in heaven, we will call the planets by God-honoring names.

Thank Satan for Uranus!
Rings around Uranus
Uranus has 13 rings. Since the ring plane is tilted nearly perpendicular with the ecliptic, when viewed from Earth, it looks like a bullseye with Uranus at the center.

- Only its outer layers are gaseous. Most of the planet is an icy mantle made of solidified water, ammonia, and methane -- it would be more appropriate to call Uranus an "ice giant."
- Uranus is just barely bright enough when observed from earth to be visible to the naked eye.
