Uranus

For my report in science, I am doing it on the planet

Uranus. As you know Uranus is the seventh planet in the solar

system. In the rest of the report I will be talking about the

size, distance, composition, surface features, and number of

moons including those topics above to desribe and compare the

moons with other planets moons. And all of these topics

talked about for Uranus will be compared with the earth.



Part 1: Size

In this section I will be talking about all the different

diameters of Uranus. Uranus has a diameter of 31,763 miles.

This planet is four times the size of the Earth. But it is just a

little bit bigger than Neptune, thats why their called twins.

The inner planets have a density bigger than 5g/cm3. The

farther a planet is from the sun, the density decreases.

Jupiter is 1.3 and Saturn is 0.69. But when you get to Uranus,

there is an increase. Uranus is 1.2g/cm3. Alot of scientists

had said that matter in the farther planets came from millions

of comets thats are made up of frozen water. Some scientists

believe that on the surface of Uranus, there is an ocean 10

thousand miles deep. Wow, could a magine swimming in that!?

Uranus' mass is 14.5 times huger than Earths. Also its

volume is 64 times bigger that Earths. Uranus is so dense that

the surface gravity is something like 1.17 times bigger than the

Earths. Uranus' escape velocity is 21.3k/sec or aprox. 48,000

miles per hour. Compared to the Earths 25,000 miles per hour.

That is a 23,000 mph difference. That is pretty damn fast.


Part II : Surface Features

The planet or Uranus is made up of hydrogen with helium

and some amounts of methane gases. The atmosphere is clouds

that travel from east to west. But this planet really has no

surface features that have ever been found. There use to be

volcanoes and craters but they have been covered up by this

big ocean scientists believe is there. They said it is 4,000 -

5,000 miles below Uranus' atmosphere. The scientists believe

it may be that deep is that they think that because of the

comets that have hit the planet.


Part III : Distances and orbital charateristics


Uranus is pretty far from most of the other planets

including the sun. It is 1.8 billion miles away from the sun.

Uranus travels around the sun in an oval orbit. Its ecentricity

is 0.046 . Unlike the Earth, it takes Uranus 84 years to travel

around the sun. Wow. The planets orbital velocity is

6.81km/sec. Also for this planet to take one rotation, it takes

17.2 hours.

As Uranus travels in its orbit around the sun, the planets

polar regions are exposed to dark and light. These four

seasons are actually quiet long. Each season has 21 years

before it switches to another season. But Winter is dark for

21 years and summer is light for 21 years. Then spring and fall

just alternate day and light. Uranus' inclination of its axis is

97.9 degree angle.


PartIV : Composition

Uranus' basic component is 75% hydrogen. The other

25% is helium and some methane gases. Uranus is called the

gas giant. The poles of Uranus are tilted at a 60 degree

angleaway from its axis. Scientists believe that there is an

ocean on Uranus and the planet has a core. They said it is

made up of metals. The ocean is 5,000 miles deep. I think it

said that it was mad up of water and ammonia. Some

scientists believe that this ocean formed from volcanic

eruptions and from large comets that collied with the planet.

Scientists also think that this ocean may be a few thousand

degrees F. Holy smokes thats got to be really uncomfortable!

Uranus has 11 rings that float around the planet. The

color is almost yellow. The last two of these rings are named

1986UR1 and 1986UR2. These were discovered by the

Voyager2 and possibly more are being discovered today. The

rings are no very bright, most are black in color. There made

up of small particles of dust and rock that have been floating

in space. Uranus' orbit drew them in and they formed a circle

around the planet. Scientists say that eventually all the
