Uranus’ StructureUranus’ Structure The Giant planets do not have
the same layered structure thatthe earthlike planets do. Theirevolution was quite differentthan 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.
AtmosphereAtmosphereThe 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
Atmosphere Cont.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
Magnetosphere of Magnetosphere of Uranus 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!
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
This is a drawing of the magnetosphere of Uranus.
Rings, Rings, Rings!Rings, Rings, Rings! Uranus has 1 prominent
ring and a lot of smallones after it
New Hubble images showthat Uranus' rings havechanged shape since 1986,when Voyager 2 firstvisited 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
Why it’s TiltedWhy 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
Discovered at Last!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 1781. It had actually been seen many times before but
dismissed as a star

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

Uranus has 3 basic sections just like EarthThe first section is made of HydrogenThe mantel is made up of frozen waterUranus has possibly the largest amount of
water covering a surface in the solar systemThe core is made of rocky material
