Uranus is the seventh planet from the Sun. It is a gas giant, the third largest by diameter and fourth largest by mass. It is named after Uranus, the Greek god of the sky and progenitor of the other gods.
NASA's Voyager 2 is the only spacecraft to have visited the planet and no other visits are currently planned. Launched in 1977, Voyager 2 made its closest approach to Uranus on January 24, 1986, before continuing its journey to Neptune.
Uranus was discovered by William Herschel on March 13th 1781. It was the first planet to be discovered by use of a telescope and was not known to the ancients as it is not bright enough to be readily visible to the naked eye,
Its orbit lies between Saturn's and Neptune's and Uranus is on average 19 times as far away from the Sun as we are:
Perihelion 2,735,555,035 km (18.286 AUs)
Aphelion 3,006,389,405 km (20.096 AUs)
Orbital period 30,707.4896 days (1 Uranus year = about 84 Earth years)
Rotation period 17 hours 14 min 24 seconds (4 Uranus days = approx 3 Earth days)
Equatorial diameter 51,118 km (4.007 Earths)
Surface area 8.084×109 km^2 (15.849 Earths)
Volume 6.834×1013 km^3 (63.086 Earths)
Mass 8.6832×1025 kg (14.536 Earths)
Uranus has 27 known moons. The names for these moons are chosen from characters from the works of Shakespeare and Alexander Pope. The five main satellites are Miranda, Ariel, Umbriel, Titania and Oberon.
The first two moons (Titania and Oberon) were discovered by William Herschel on March 13, 1787. Two more moons (Ariel and Umbriel) were discovered by William Lassell in 1851. In 1852, Herschel's son John Herschel gave the four then-known moons their names. In 1948 Gerard Kuiper discovered the moon Miranda.
Uranus has a faint planetary ring system, composed of dark particulate matter up to ten meters in diameter. This ring system was discovered in March 1977 by James L. Elliot, Edward W. Dunham, and Douglas J. Mink using the Kuiper Airborne Observatory.
As of 2005, 13 rings had been identified. In December 2005, the Hubble Space Telescope photographed a pair of previously unknown rings. The largest is twice the diameter of the planet's previously known rings. The new rings are so far from the planet that they are being called Uranus's "second ring system."
So Saturn is not the only planet with rings in our solar system!
Visibility. The brightness of Uranus is between magnitude +5.5 and +6.0, so it can be seen with the naked eye as a faint star under dark sky conditions. It can be easily found with binoculars. It looks pale blue, as does Neptune,

I do so hope this isn't what I think it is, a puerile schoolboy joke about naughty bits of the human anatomy, because some people have taken the time and trouble to research and write a serious answer in the hope of interesting you in our Solar System neighbour (about which most of us know very little) and with the aim of enabling you to observe it and find out more about it.
I will be disappointed if you award 10 points for a facile answer making a predictable wisecrack, If you are going to do that, I would rather the voters decide which is the most interesting and informative of the answers as that would show the serious answerers more respect.
Did you know Uranus had rings, like Saturn? I certainly didn't, so I am glad you asked the question, as I have learned something from the answers it has stimulated. That is what Yahoo Answers should be all about!

Why is this important to you? Are you asking what constellation it is in?
Aquarius.
Right Ascension 23h 01min 54.3s
Declination -07° 04' 49"
Get out your star map and look up these coordinates. Then use that with a telescope or binoculars to locate Uranus in the sky.
That IS what you asked, right?

Uranus’s orbit lies outside the Earth’s. It lies far outside, for the aquamarine planet never comes within 2.5 billon kilometers of us. This distance makes Uranus, the farthest planet that can be regularly seen from Earth without magnification.
