3. About  Uranus is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both have different bulk chemical composition from that of the larger gas giants Jupiter and Saturn.

4. What is Uranus next to?

5. Temperature  It is the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 degree farahiant, and has a complex, layered cloud structure, with water thought to make up the lowest clouds, and methane the uppermost layer of clouds.  Space School - Uranus Space School - Uranus

6. How old is Uranus?  Uranus is 4.5 billion years old. Uranus was formed at the same time as the rest of the Solar System, from a large spinning disk of gas and dust.

7. What its made of  Like the other gas giants, it has a hydrogen upper layer, which has helium mixed in. Below that is an icy “mantle, which surrounds a rock and ice core. The upper atmosphere is made of water, ammonia and the methane ice crystals that give the planet its pale blue color. Uranus' atmosphere is about 83% hydrogen, 15% helium and 2% methane.

8. Interesting facts  Uranus rains diamonds. Diamonds as the ones use to give as a special gift to someone!!  With minimum atmospheric temperature of -224°C Uranus is nearly coldest planet in the solar system  Uranus has 27 moons. Uranus' moons are named after characters from the works of William Shakespeare and Alexander Pope

9. The Rings of Uranus  Uranus has very faint rings. The inner part of the rings are narrow and dark and the outer rings are brightly colored. The rings of Uranus were discovered on March 10, 1977, by James L. Elliot, Edward W. Dunham, and Jessica Mink. More than 200 years ago, in 1789, William Herschel also reported observing rings; some modern astronomers are skeptical that he could have actually seen them, as they are very dark and faint, others are not.

12. Moons of Uranus UUranus has 27 known natural moons. The names of these satellites are chosen from characters in the works of Shakespeare and Alexander Pope. The five main satellites are Miranda, Ariel, Umbriel, Titania,and Oberon. The Uranian moon system is the least massive among those of the giant planets the combined mass of the five major moons would be less than half of Triton which is the largest moon of Neptune. Uranus, its rings and Moons - Voyager 2

13.  These moons were discovered in 1851 by William Lassell (Ariel and Umbriel) and in 1948 by Gerard Kuiper (Miranda)  These five have planetary mass, and so would be considered (dwarf) planets if they were in direct orbit about the Sun. The remaining moons were discovered after 1985, either during the Voyager 2 flyby mission or with the aid of advanced Earth-based telescopes.

17. BANG!  Uranus is 15,759 miles long.  It takes approximately 84 years for Uranus to orbit around the biggest star in our solar system also know as the SUN!!!  baby 84 year old man

18. When was it discovered??? Uranus was discovered on March 13 th 1781. (Christians birthday I still take late gifts) The noble man who discovered this blue gaseous planet goes by the name of William Herschel. Giant Exo-Uranus Discovered!

19. Target Questions  Which is not true of all the inner planets?  Answer: Smaller, Harder, and Denser  Uranus axis is about how big?  Answer: Uranus axis is almost parallel to the plane of its orbit.
