5 Uranus’ Structure The Giant planets do not have
the same layered structure that the earthlike planets do. Their evolution was quite different than that of the earthlike planets, and they have much more gas and ice inside. Uranus's interior is primarily made of methane ice. Motions in the interior of Uranus help form the magnetosphere of Uranus. Heat generated within Uranus helps form the unusual winds of the atmosphere.

6 Atmosphere The plain aquamarine face of Uranus proves the fact that there are clouds covering Uranus Because the face of Uranus is all alike that shows that the planet's atmosphere is mostly made up of one thing, methane. The planet appears to be blue-green because the methane gas of the atmosphere traps red light and does not allow that color to escape

7 Atmosphere Cont. High in its atmosphere there is also ethane, which can fuel automobiles on Earth Like Jupiter and Saturn, the basic weather of Uranus can be described as a striped pattern of winds. This means that, even though the pattern is hard to see, Uranus is striped, just like Jupiter and Saturn

8 Magnetosphere of Uranus
The magnetosphere of Uranus is medium sized, but still much bigger than the Earth's. It holds all of Uranus' moons It is believed to be made in the middle of the planet, and with ice, rather than with iron at the core The magnetosphere of Uranus has a very strange tilt. The extreme tilt, combined with the extreme tilt of Uranus itself, makes for a completely strange magnetosphere, one which has twisting structure!                                                                    

9 Magnetosphere Cont. Mathematical theory suggests that the rings of Uranus sweep the particles in the magnetosphere into the atmosphere The Aurora on Uranus is difficult to detect, and so are radio signals from Uranus, which means that the magnetosphere of Uranus may be almost empty

10                                                                 This is a drawing of the magnetosphere of Uranus.                                                                    

11 Rings, Rings, Rings! Uranus has 1 prominent ring and a lot of small
ones after it New Hubble images show that Uranus' rings have changed shape since 1986, when Voyager 2 first visited the gas giant. Uranus' inner rings are much more prominent than before Uranus' outermost ring is blue, just like Saturn’s E-ring Uranus's rings stand out strongly in the infrared because their icy material is efficient at reflecting sunlight at this wavelength

12 Why it’s Tilted Astronomers think Uranus was hit by a really big 'planetessimal' soon after the solar system was formed, but before its moons were born. The thing that hit it put matter in orbit around the new tilted Uranus so that the moons could eventually form out of this ejected material left over from the collision. It seems that all of the planets have at one time been hit by BIG OBJECTS nearly as big as they are. For the Earth, this resulted in the formation of the Moon

13 Discovered at Last! Uranus was the first planet discovered in modern times. It was found accidentally by William Herschel while he was searching the sky with a telescope in It had actually been seen many times before but dismissed as a star

14 Just the Facts Diameter- 51,118 km Density- 1.29 g/cm3
Mass x 1025 kg Volume x 1013 km3 Atmosphere- Hydrogen, Helium, Methane Winds- Up to 160 m/s Moons- 27 Distance from Sun- 2,870,990,000km Orbital Period- 84 Years, 3 Days, Hrs. Rotation Hours Tilt ° Magnetic Field- Extends 15 times planet radius

15 Burr! Its Cold!! Uranus’ mean tempature is 58K
It has been recorded as low as 49K however! That is in Kelvin, which has 0 as no motion. That’s what I call cold!!

16 Its Name’s History The name Uranus comes from a Greek God named Ouranos, also spelled Uranus like the planet. This is the oldest God ever worshiped He was the embodiment of the sky or heavens, and known as the god of the sky. He was the first son of Gaia (the earth) and he also became her husband His offspring included the Cyclopes and Hecatonchires, who each had one hundred hands and fifty heads The story goes that he was afraid of his sons strength. So he hid them inside Gaia (Earth).

18 Interior Uranus has 3 basic sections just like Earth
The first section is made of Hydrogen The mantel is made up of frozen water Uranus has possibly the largest amount of water covering a surface in the solar system The core is made of rocky material
