Uranus: The Ringed Planet That Sits on its Side
The upper atmosphere of water, ammonia and methane ice crystals gives Uranus its distinctive pale blue color. Uranus is the second least dense planet in the solar system, after Saturn. The Voyager 2 is the only spacecraft to have flown by Uranus. This happened in and it flew past the planet at a distance of around 81, km. The cold methane gas is what gives Uranus its blue-green color. The rapid rotation of Uranus causes winds up to kilometers per hour to blow in its atmosphere. Uranus has eleven known rings which contain dark, boulder-sized particles. Uranus has 27 named moons. Some of these moons are less than kilometers wide and black as coal.
The seventh planet in the solar system — and the largest of iss ice giants — Uranus has an atmosphere more comparable with Neptune than with Saturn and Jupiter. Known as ice giants, the two most distant planets from the sun have atmospheres that are heavily dominated by ices.
The bizarre orientation of the planet, which orbits the sun tipped on its side, reveals that its inner core has a stronger influence on its weather patterns than the distant star. Uranus' atmosphere is predominantly made up of hydrogen and helium. Unlike Jupiter and Saturn, these light gases dominate only the outer edges of the planet, but are not a significant contributor to the rocky interior.
It's kind of a pale blue planet. It's the real pale blue dot. Traces of hydrocarbons are also present in the air around Uranus. Ices made up of water, ammonia, and possibly methane also exist in the atmosphere.
As on Earth, the atmosphere of Uranus is broken into layers, depending upon temperature and pressure. Like the other gas giants, the planet doesn't have a firm surface. Scientists define the surface as the region where the atmospheric pressure exceeds one bar, the pressure found on Earth at sea level.
Just above the "surface" of Uranus lies the troposphere, where the atmosphere is the densest. The temperature ranges from minus degrees Fahrenheit minus degrees Celsius to minus F minus Cwith the upper regions being the coldest.
This makes the atmosphere of Uranus the coldest in the solar system. Within the troposphere are layers of clouds — water clouds at the lowest pressures, with ammonium hydrosulfide clouds above them. Ammonia and hydrogen sulfide clouds come next. Finally, thin methane clouds lay on the top. The troposphere extends 30 miles 50 kilometers from the surface of the planet. Radiation from the ruanus and from space heats the stratosphere of Uranus from minus F minus C to minus F minus C.
The stratosphere contains ethane smog, which may contribute to the planet's dull appearance. Acetylene and methane are also present. These hazes help warm the stratosphere. Hydrocarbons are less abundant in the atmosphere of Uranus than they are of other giant planets, however.
The stratosphere reaches almost 2, miles km above Uranus. The thermosphere and corona of Uranus reach temperatures of 1, F Calthough scientists are unsure as to the cllor. Because the distance to Uranus from the sun is so great, the amount of heat coming from the star is insufficient to generate such high temperatures.
Extending twice as far from what is the color of uranus the planet center of the planet as its surface, the far-reaching outer layers are unique to Uranus. They create a drag on the ring particles that orbit the planet. Although the planet looks to be a solid shade of blue, it contains stripes like Jupiter and Saturn. But the bands are faint, and are only seen with enhanced images.
Uranjs with other gas giants, the zones form as gases within the region warm and rise, while in the belts, the gases fall back to the planet how to make a salvation bracelet they cool.
In the belts, the whah blow east, while they travel west within the zones. When Voyager 2 flew by the planet init only observed 10 cloud patterns on the planet. As technology improved, higher resolution images taken from Earth revealed fainter clouds. Simon said that temperature is a large part of the reason for Uranus' blandness.
The ice giant doesn't have a lot of heat. In fact, it is the only planet that doesn't give off more heat than plaet receives from the sun, she said. That slows down the rise and fall of heat that would otherwise drive storms. So, you co,or see the bright clouds on Uranus that you see on the other planets," Simon said. While storms on Uranus aren't as numerous as they are on other worlds, that doesn't mean the planet doesn't have occasional activity.
Inseven years after the planet made its closest approach to the sun, astronomers spotted active weather spots on the urans giant. Why we see these incredible storms now is beyond anybody's guess. But seeing details on Uranus and Neptune are the new frontiers for us amateurs, and I did not want to miss that. Storms aren't the only bright spot on Uranus. When a team led by an astronomer from Paris Observatory took a second look at the auroras using Hubble's ultraviolet capabilities, they "found themselves observing the most intense auroras ever seen on the planet," NASA said in a statement.
Unlike other planets in the solar system, which spin along the same plane as the sun, Uranus, discovered inwas knocked on its side by a collision soon after its formation. With its equator down, the what is the color of uranus the planet appears to roll around the sun. This means that only one pole at a time faces the distant star. The planet og spins backwards as a result, so that if it rotated with its equator along the plane of the solar system, the sun would rise what does a barometer measure the west rather than the east.
On most what time does tcf bank open on sunday, the equator receives the most sunlight, causing warm air to rise and move to the poles. But the equator of Uranus hardly ever faces the sun. Urwnus, the warm air should rise from the pole that faces the sun, and fall back at the cooler pole.
But the bands and zones of Uranus reveal otherwise. The planet's stripes rotate around the equator the same way they do on Jupiter and Saturn.
Instead sunlight, the interior heat of the planet appears to drive its weather. Join our Space Forums to keep talking space on the latest missions, night sky and more!

Jul 10, · Uranus is blue-green in color, as a result of the methane in its mostly hydrogen-helium atmosphere. The planet is often dubbed an ice giant, since at least 80% of its mass is . The color of Uranus is blue due to the fact that it has an atmosphere made up of water, ammonia, and methane. Uranus may be one of the “gas giants” but it is also the lightest in mass. The year that Uranus was discovered they also discovered a new element and named it Uranium after the planet. Jan 04, · Uranus is Neptune’s near twin in size and composition. The third most abundant component of Uranus’s atmosphere is methane. Methane has prominent absorption bands in the visible and near-infrared, making Uranus aquamarine or cyan in color. Between - , the closest approach of Uranus to Earth will happen in at a distance of AU.
Listen to an audio version of this page. Sorry, your browser does not support the audio element, please consider updating. Uranus tilts over so far on its axis that it rotates on its side.
Because of this, its poles are sometimes pointed almost directly at the Sun. Uranus' atmosphere is made up of hydrogen, helium, and methane. The temperature in the upper atmosphere is very cold. The cold methane gas is what gives Uranus its blue-green color. The rapid rotation of Uranus causes winds up to kilometers per hour to blow in its atmosphere. Uranus has eleven known rings which contain dark, boulder -sized particles. Uranus has 27 named moons.
Uranus is one of the smaller gas giants in our solar system, but it is still large enough to hold 64 planets the size of Earth. A Question What makes Uranus look blue-green in color? Return to the StarChild Main Page. Go to Imagine the Universe!
