Uranus, named after the father of the Roman god Saturn, is the seventh planet in the solar system and the third of gas giants. It is the third-largest planet with a diameter and at the same time the fourth most massive planet.

 

 

URANUS FACTS

1

William Herschel discovered Uranus in 1781. The planet is too weak for an ancient civilization to see.

Herschel himself believed that Uran was originally a comet, but a few years later he was confirmed as a planet – making Uranus the first planet discovered in modern history.

 

The original name proposed by Herschel was “Georgian Sidus” after King George III, but the scientific community did not take it.

Uranus revolves around its own axis once every 17 hours and 14 minutes. Like Venus, it rotates in the reverse direction, which is opposite to the direction of the Earth, and the other six planets rotate.

3

Uranus needs 84 days on Earth to circumnavigate the Sun. Its axis is 98 degrees, which means it almost lies sideways as it revolves around the Sun. This means that the northern and southern poles of Uranus lie near the equator on Earth.

4

The Uranus facts, The collision could have caused Uranus’ unusual inclination. The theory is that planet Earth could collide with Uranus, which forced the axis to drastically shift.

 

5

Uran’s wind speeds can reach up to 900 km per hour. That’s about 560 miles an hour.

The Uranian mass is about 14.5 times the Earth’s mass, making it the lightest of the four gaseous giants of the outer Solar System.

Uranium is often referred to as the “ice giant”. Although it has a water layer and helium higher than other gaseous giants, Uranus also has an ice cloak that surrounds its stone and iron core.

The upper atmosphere of water, ammonia and methane ice crystals gives Uranus a characteristic pale blue color.

Uranus is the second least dense planet in the solar system after Saturn.
Voyager 2 is the only spacecraft to fly through Uranus.

It happened in 1986 and flew around the planet about 81,500 km. This mission drew the first similar images of the planet, its ring system, and its moons in orbit.

Uranium has 13 currently known rings. All except the two Uranians are extremely narrow – they usually have a width of several kilometers.It believes that the rings are probably quite young.

 

The matter in the rings is thought to be part of the moon that has been broken by high-velocity impacts with an object such as a comet or asteroid. The chemical element Uranus facts, discovered in 1789, was named after the newly discovered planet Uranus.

Uranus is the coldest planet in the solar system. The minimum surface temperature of Uranus is -224 ° C – making it the coldest of the eight planets. The upper atmosphere covers with a mist built mainly of methane, which hides storms taking place in the clouds.

Another Uranus facts, The Uranus moons are named after characters created by Alexander Pope and William Shakespeare. For example Oberon, Titania, and Miranda.

All these worlds frozen with dark surfaces, and some are a mixture of ice and rocks. The most interesting of Uranian moons are Miranda, which has ice canyons, terraces, and many strange-looking surfaces.

 

 

Atmosphere Uranus Facts

Because of its raw blue appearance, the atmosphere of Uranus was much more difficult to observe that, for example, Jupiter or even Saturn.

Fortunately, the Hubble Space Telescope gave much more information about the structural nature of the Uranian atmosphere.

 

Thanks to more advanced imaging technologies than Earth or Voyager 2 telescopes, Hubble has shown that there are parallel latitudinal bands similar to those found on other gaseous giants. In addition, the winds associated with these bands can reach speeds of over 576 km / h.

The reason for the monotonous mood is the composition of the highest atmosphere layer.

Visible cloud layers consist mainly of methane, which absorbs the visible wavelength corresponding to the red color. So the reflected waves are blue and green.

 

Under this external methane layer, the atmosphere consists of approximately 83% hydrogen (H2) and 15% helium with traces of methane and acetylene. This composition is similar to that of other gas giants.

 

The atmosphere of Uranus is drastically different in other respects. While the atmosphere of Jupiter and Saturn is mainly gaseous, Uranium contains much more ice.

This means that the atmosphere of Uranus is extremely cold. Indeed, at about -224 ° C, its atmosphere is the coldest in the Solar System.

 

 

Interior Uranus Facts

The interior of Uranus consists of two layers: the core and the mantle. Current models suggest that the core consists mainly of rocks and ice and has a mass of about 55 Earth masses.

It is believed that the planet’s coat is 8.01 x 1024 kg or about 13.4 times more than the Earth’s mass.

 

In addition, the coat consists of water, ammonia and other volatile components.

What distinguishes Uranus’ mantle from Jupiter and Saturn is that it is icy, though not in the traditional sense. Instead, the ice is very hot and thick. The coat has a thickness of 51.1 km.

 

What is most surprising is the interior of Uranus and one of the most distinguishing features in relation to other gas giants is that it does not emit more energy than it receives from the Sun.

 

Considering that even Neptune, which is very similar to Uranus, produces about 2.6 times the amount of heat it receives from the Sun. The scientists intrigued by the low heat that Uranus generates.

 

There are two popular theories of this phenomenon. The first one says that Uranus was hit by a large body, dissipating in space most of the heat that usually keeps the planets from their formation.

The second theory claims that there is a barrier that prevents internal heat from entering the surface of the planet.

Orbit Uranus Facts

When Uranus facts were discovered, it increased the radius of the known solar system almost twice. This means that the Uran orbit has an average of about 2.87 x 109 km.

 

The consequence of such a huge distance is that the sunlight needs about two hours and forty minutes to reach Uranus and it is almost twenty times longer than sunlight reaches the Earth! This huge distance also means that the year on Urana lasts almost 84 Earth years!

 

At 0.0473, Uranus’s orbital eccentricity is slightly less than Jupiter’s eccentricity of .484, making it the fourth most orbiting planet on all planets.

As a result of the rather small Uranus orbital ecosystem, the difference between its perihelion of 2.74 x 109 km and the appeal of 3.01 x 109 km is only 2.71 x 108 km.

 

 The axis of rotation for each planet other than Uranus facts is roughly perpendicular to their orbital plane. However, the Uranian axis is tilted almost by 98 °, which means that Uranus rotates on its side.

 

As a result, the North Pole of Uranus points to the Sun for half a year, while the South Pole points to the Sun for the second half of the year.

What’s more, because of this extreme rotation. The Uranus does not have days like those on other planets, and that is, the sun does not rise and does not set on other planets.

 

Rings Uranus Facts

Although Saturn’s rings have been known for some time, it was not until 1977 that the rings of the planets surrounding Uranus were discovered. The reason for this is twofold: distance from the Earth and low light reflectance.

 

Nevertheless, the Voyager 2 probe identified two more on its mission in 1986, followed by the discovery by the Hubble Space Telescope of two additional rings in 2005. The total number of known rings is now at the age of thirteen, of which the largest and the brightest in the ring epsilon.

 

Uranus rings differ from the rings around Saturn in both particle size and particle composition.

First, the particles that makeup Saturn’s rings are small, while Uranus facts on rings contain many bodies with a diameter of up to twenty meters.

Second, Saturn’s ring particles make with ice. Uranus, however, consists of both ice and significant dust and debris.
