Why is Uranus considered an ice giant?

Uranus is considered an Ice Giant because of its sub-zero temperatures and it

its high composition of ice.

Edit: It isn't quite that simple. The "ices" will be at a high temperature deep

inside Uranus. But the very high pressures there keep them as solids. It's

an example of how scientists use words in ways that can mislead people.

Were Uranus and Mother Earth husband and wife?

Yes - at one stage of her many phases and activities but Gaia (mother earth) became tired of Uranus attacking their children and got the youngest son Cronus to do him in and replace him.

What are facts about Uranus?

*(Facts about the planet Uranus - for the Greek god, see below)

  • Uranus is a gas planet. But beneath its upper atmosphere is a dense ocean of water and ammonia over a small rocky core.
  • It is the 7th planet from the Sun.
  • Uranus was not discovered until 1781, it looked like a dim star. Discoverer William Herschel originally named the planet Georgium Sidus, after King George III of England.
  • Its modern name comes from the Greek titan Uranus (Ouranos)
  • It is 1,784 million miles away from the Sun (1.8 billion miles).
  • It could fit 14.5 Earth's inside of it.
  • Uranus has 27 known moons.
  • Uranus has 11 faint rings, like those of Saturn but narrower.
  • It takes the light from the Sun 2.5 hours to reach Uranus.
  • Its orbital period is 84.32 Earth years.
  • Its axis is at 98 degrees, almost vertical.
  • Although it is larger than Neptune, Neptune has more mass.
  • Winds in the cloud layers can reach speeds of 860 kilometers an hour (540 mph).

The average distance between the sun and Uranus is 2,870,972,200 km or 1,783,939,400 miles or 19.19 AU.

Uranus has the second largest ring system after Saturn.

Uranus is very cold, since it is so far from the sun, the cloud tops are only around -224 °C. The core of the planet is around 5000 degrees Kelvin (roughly the same in °C). Uranus does not generate much internal heat, since it is not contracting much (unlike Jupiter or Saturn, which have much higher core temperatures).

Uranus is the third largest planet, but the fourth most massive. Uranus is less massive than Neptune, but has a bigger volume than Neptune.

Uranus' atmosphere is mainly Hydrogen (around 83%), Helium (around 15%) and Methane (around 2.3%). The methane gives it its light green/blue color.

Both Venus and Uranus have a retrograde axial spin, they rotate clockwise when viewed from above their north pole. All of the other planets rotate anticlockwise (counter clockwise). This occurs because Uranus is tilted on its side by over 90 degrees, probably due to a collision during the formation of the solar system.

Uranus has only been visited once by spacecraft, by Voyager 2 in 1986.

The outer layer of clouds around Uranus have the frigid temperature of space, only about 49 degrees Celsius above absolute zero. It is the coldest planet in the solar system.

William Herschel discovered the planet on March 13, 1781. Through a telescope, it is a light green color and has very faint rings like those of Saturn. The rings were first examined close up by the unmanned probe Voyager 2 in 1986.

The God Uranus

Uranus is the ancient Greek deity of the Heavens, the earliest supreme god. Uran us was the son and mate of Gaia, and the father of Cronus (Saturn) and of the Cyclopes and Titans (predecessors of the Olympian gods).

Also, a day on Uranus is 17 Earth hours, but a day on the north pole of Uranus can be as long as 24 Earth years.

What are Mars' rotation and revolution periods?

Mars' rotation period (the time it takes to spin once on its axis) is 24 hours 39 minutes and 35 seconds.

Mars' revolution period (the time it takes to make one orbit round the Sun) is 686.971 (Earth) days, which is the same as 1.8808 (Earth) years.
The rotation period of Mars is the time it takes to make a complete spin around its axis. (It takes a couple of minutes longer to make a complete day and night.) The rotational period of Mars is about 24 hrs and 37 mins (3% longer than an Earth day).

The revolution period of Mars is the time it takes to make a complete orbit around the Sun and to finish a complete year. The revolution period of Mars is 687 earth days (1.67 earth years).
Similar to Earth, or exactly 24 hours, 37 minutes, and 22 seconds.

Homeschooling
Planet Uranus

How many hours each day do you get homeschooled?

I think that depends. Many of my homeschooling friends work for as little as 2-3 hours a day for five days a week, and others work for 5-6 hours a day for three days a week, etc. Other homeschooling families make school a hands-on part of everyday life, so the students are "in school" almost 24/7. ;-) It really depends on how much work the parent sees fit to assign, what kind of work the parent assigns, and on how fast the child/children can work.

I am homeschooled and will be a Jr in high shool. I do my school pretty much in my spare time because I am so busy. I would say I work on my school on average 6 hours a day. (five days a week) What it really comes down to is if i get all my assigned work done, rather than how long i spend doing it. For example it might take me an hour to do my math one day, but the next day it takes me two hours. That is why the time varies so much. It just depends on the student.

A guideline is 4.5 hrs max. Miz

I homeschool my 7 kids for 7 hours. I guess with 7 kids you just have to get the job done and for me the only was to do that is to wxtend our school by an hour.

Temperature
Planet Uranus

What is Uranus' temperature?

The temperature would vary depending on where in the atmosphere you measured it.

The upper atmosphere of Uranus is the coldest in the Solar System, with a minimum temperature of 49 K. It has a complex cloud structure with water clouds presumably being the deepest and methane clouds at the top.

  • The minimum temperature is -224 °C (-371 °F, 49 K).
  • At the pressure level equal to Earth's at sea-level (1000 millibars), it is -197 °C (-322 °F, 76 K).
  • Uranus' water-ammonia "ocean" is extremely hot, up to 6650 °C / 12,000 °F near the rocky core (which cannot be directly observed).
The temperature on Uranus is usually very cold, but in the oceans of Uranus it is very hot reaching 8000 degrees Celsius. The lowest temperature ever recorded is -224. It is usually around -120

-355 degrees, it rises fast and can also reach 4200 degrees in the ocean and can become 12600 degrees at the core

The temperature of the atmosphere in Uranus is about -355 degrees F (-215 degrees C). In the interior, the temperature rises rapidly, reaching perhaps 4200 degrees F (2300 degrees C) in the ocean and 12,600 degrees F (7000 degrees C) in the rocky core.

Uranus' temperature is -98 Degree Celsius.
The "surface" of Uranus is hard to define, but these are the sorts of temperatures:

Highest, about -216 degrees Celsius.

Lowest, about -224 degrees Celsius.

There's not much difference, as you can see.
There's very little variation in the surface temperature. The average is usually

given as about minus 215 degrees Celsius.

What are the moons of Uranus?

As of 2009, Uranus has 27 known moons, which are named after characters from works by William Shakespeare and Alexander Pope. (Not one is named Romeo.) The five largest moons of Uranus are Titania, Oberon, Umbriel, Ariel, and Miranda. The other 22 are quite small.

Titania and Oberon were discovered in 1789 by William Herschel.

Ariel and Umbriel were discovered in 1851 by William Lassell.

Miranda was discovered in 1948 by Gerard Kuiper.

The remaining moons were discovered after 1985.

The 13 inner moons are intricately involved with the 13 rings of Uranus.

In order, moving out from the planet, they are:

  1. Cordelia
  2. Ophelia
