The Planet

Like Jupiter and Saturn, Uranus is a gas giant. But Uranus is a little different. Unlike all the other planets and most of the moons in our Solar System, Uranus spins on its side. It is believed that long ago a very large object smashed into this planet. The crash was so powerful that it completely changed the direction of Uranus' planetary rotation. However, a more recent theory is that the extreme tilt of Uranus' axis may have been caused by a large moon that was slowly pulled away from the planet by another large planet long ago when our Solar System was still new.

History

• William Herschel discovered Uranus on March 13, 1781.

• Uranus was named after the Greek god deity who was the god of the sky

• This is Uranus's symbol

Solar System• Uranus is the 7th planet from the sun.

Uranus is 1,787,485,510 miles (2,876,679,082 km) away from the sun• It takes Uranus 84 years to circle around the sun

• Below is a picture showing Uranus's relationship in space to other

planets.

Uranus's Measurements

• Uranus is the third largest planet in the solar system, after Jupiter and Saturn. Uranus is about four times bigger than Earth. Its diameter at the equator is about 31,763 miles 51,118 kilometers as measured at the level of the atmosphere where the pressure is the same as at sea level on Earth. The planet is slightly larger than Neptune but Neptune is about 1.2 times more massive. Uranus's' density is quite low only about 1.3 times that of water, compared with 1.6 for Neptune and 5.5 for Earth.

• Mass - Metric: 86,810,300,000,000,000,000,000,000 kg Volume- metric- 68,334,355,695,584 km3

• Surface Gravity Metric: 8.87 m/s2

• Orbit Circumference Metric: 18,026,802,831 km

The atmosphere and core of Uranus

• Uranus is shrouded in an icy cloud layer made up of frozen methane, ethane, and acetylene circling this planet at about 185 mph (300 kph. Uranus' icy and cold atmosphere consist of 83% hydrogen,15% helium, and 2% methane.

• Uranus has a molten rocky core about 10,500 miles (17,000 km) in diameter and about 12,500°F (6927°C). This core may have a mass five times greater than the mass of the Earth.

Surface Conditions or Uranus

• Uranus is not the farthest planet from the Sun but it is the coldest planet in the Solar System.

• The average temperature of the surface of Uranus is 49° Kelvin or -224° Celsius.

• Uranus is so cold because its core.Uranus is only 5000° K, compared to Jupiter, which as a core temperature of 30000° K.

Moons• Uranus has 27 named after characters from the works of

William Shakespeare and Alexander Pope. Scientists believe that Uranus has more than 30 moons but they have not been discovered yet

• Moon names• Caliban, Stephano, Trinculo, Sycorax, Margaret, Prospero,

Setebos, Mab, Pertida, Cupid, Francisco, Ferdinand, Oberon, Titania, Umbriel, Ariel, Miranda, Puck, Rosalind Portia, Juliet ,Desdemona ,Cressida, Bianca ,Ophelia and Cordelia.

Rings

• Uranus has different rings than Jupiter and Saturn. Uranus's rings are very small and spaced out so it looks like there are several skinny rings with big gaps in-between.

• Astronomers think that the rings of Uranus are very young, and probably formed recently, and not with the planet.

What would happen if a human went to Uranus?

If a human went on Uranus they would freeze because of the low temperatures on Uranus. A human would also choke because the extremely low oxygen levels. In order to explore Uranus safely a human would need an oxygen tank and a body warmer along with probably 200 winter coats.

Fun facts

• If you way 100 pounds on earth you will weight 91 pounds on Uranus.

• It will take 141/2 earths to fill Uranus• Summer on Uranus lasts 42 years.• Uranus was the first planet discovered in the

modern age.

• A day on Uranus is 17 hours, 14 minutes and 24 seconds.

Weather on Uranus

• Here’s the scoop about weather on Uranus. A thick, tempestuous atmosphere with winds blowing at a clip of 560 mph; massive storms that would engulf continents here on Earth, and temperatures in the -220 degrees Celsius -360 degree Fahrenheit
