**Science Teacher - "Okay class, have you heard,** A second set of two rings has been discovered at roughly 100,000 km radius?"

Uranus' bluish color is due to the absorption of the red light from the sun, and reflection of the blue light from the sun back into space

 * Jack lissauer, and a few other men have recently discovered two small moons orbiting our planet Uranus.

__Uranus's moons: Miranda, Ariel, umbriel, Titania, Oberon, This is the order of the moons from increasing distance from the planet, Uranus.__**

Average Distance from the sun: Metric - 2,870,972,200km English - 1,783,939,400mi__ Mass Of Uranus - 86,832,000,000,000,000,000,000,000Kg

The blue-green color, is from methane gas.
 * Uranus has a bluish greenish color to it.

Uranus has some of the brightest clouds in the outer solar system, Discovered on March 13, 1781**

It has a mean distance from the Sun of 2.87 billion kilometers (1.78 billion miles). It rotates about its axis once every 17 hours 14 minutes. Uranus has at least 22 moons. The two largest moons, Titania and Oberon, were discovered by William Herschel in 1787.
 * The atmosphere of Uranus is composed of 83% hydrogen, 15% helium, 2% methane and small amounts of acetylene and other hydrocarbons. Methane in the upper atmosphere absorbs red light, giving Uranus its blue-green color.**

 * Uranus

Most people are likely to giggle at the incorrect pronounced name, it was originally suppost to be named, "Georgium Sidus", to honor an English King

 * //Once considered one of the blander-looking planets, Uranus (pronounced YOOR un nus) has been revealed as a dynamic world with some of the brightest clouds in the outer solar system and 11 rings. The first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel. The seventh planet from the Sun is so distant that it takes 84 years to complete one orbit. Uranus, with no solid surface, is one of the gas giant planets (the others are Jupiter, Saturn, and Neptune).

The atmosphere of Uranus is composed primarily of hydrogen and helium, with a small amount of methane and traces of water and ammonia. Uranus gets its blue-green color from methane gas. Sunlight is reflected from Uranus' cloud tops, which lie beneath a layer of methane gas. As the reflected sunlight passes back through this layer, the methane gas absorbs the red portion of the light, allowing the blue portion to pass through, resulting in the blue-green color that we see. The planet's atmospheric details are very difficult to see in visible light. The bulk (80 percent or more) of the mass of Uranus is contained in an extended liquid core consisting primarily of 'icy' materials (water, methane, and ammonia), with higher-density material at depth.

In 1986,//** **//Voyager 2//** **//observed faint cloud markings in the southern latitudes blowing westward between 100 and 600 kilometers (60 and 400 miles) per hour. In 2004, the Keck Observatory in Hawaii used advanced optics to capture highly detailed images of Uranus as the planet approached its southern autumnal equinox, when the equator will be vertically illuminated by the Sun.//**
