The coldest planet in the solar system

If you decide to spend a vacation on a nearby planet, then you need to find out what the climate on a particular celestial body. This, of course, a joke, but many people know that the majority of planets in our galaxy have a temperature incompatible with human life. And the coldest planet in the solar system is, of course, Uranium.

It’s a shame, but still the routes of interplanetary expeditions bypassed the Uranium side. Earth sent space probes to Mars, Venus, mercury, Saturn, Jupiter. And even Pluto, which has lost the title of the planet 8 years ago. The only time in the vicinity of the coldest planets flying apparatus «Voyager 2», occurred in 86 year of the last century. And then, the spacecraft flew past on the way to the edge of the Solar system.

Uranium

«Voyager 2» was launched in 1977 and it took nine years before it reached the planet Uranus, and at the end of January 1986, the spacecraft flew at the distance of 81 thousand kilometers from the surface of the clouds at a speed of thirteen miles per second. In the few hours that Voyager flew past the coldest planet, he transmitted to Earth information that is the basis of our present knowledge about Uranium.

Uranium

In General, the plans of NASA was to study the four planets. And the launch of the space funds were dedicated to the «parade of planets», an event that occurs once in two hundred years. The gist of it is that if viewed from the Earth, the four largest planets are on the same line.

It is recognized that Uranium unfairly ignored by. This planet is no less interesting and amazing than all others.

Uranium, which is a plague of toxic gases – methane, ammonia, hydrogen sulfide, more than 60 times larger than the Earth by volume. On the surface of this giant has no solid ground, no fluid – there are no borders between the different States of matter that forms the planet. If you somehow find yourself on the planet, as it passes into the nucleus of Uranium, you will be able to observe, as the substance gradually passes from a gaseous to a liquid state, and the closer to the center becomes more dense.

Winter length of 500 months

Uranium

Around the coldest planet in the Solar system revolves twenty-six small satellites. Also Uranium is inherent in the ring system, however, they are inferior as spectacular as the rings of Saturn. The planet’s weak magnetosphere. Uranium has another feature – it seems to be on his side. Due to the fact that the axis of Uranus towards the sun, one part of it for 42 earth years it has not returned, and all the while shining never rises above the horizon. When spring comes and autumn, the Sun rises every nine hours.

The discovery of the planet

Uranium

And once upon a time people did not even know about the existence of this planet. They knew that on the horizon there are five planets that are visible to the naked eye, if at the time of observation of the sky they are not obstructing the disk of the star. Are Mercury, Venus, Jupiter, Saturn, Mars.

Uranium

The Uranus was built in the late eighteenth century, and we owe it to William Herschel. A cloudless spring night, the astronomer peering into the telescope – it seems that in the constellation of Gemini there is an interesting point. Subsequent nights showed that the object moved through the heavens. Herschel decided that it was a comet.

This news made the best mathematicians of that age to sit behind the calculations – in those days such work was very time consuming. While scientific minds have studied numbers, the astronomer continued observation of an unusual celestial object. Few months it took to Russian and French scientists have shown that Herschel discovered a new planet located behind the Saturn.

Subsequently it became obvious that to William’s Uranus was observed multiple times, but each of them took the planet behind the star. Well, this phenomenon in astronomy are not uncommon.

Uranium — what is it?

Uranium

Hydrogen, helium, methane are the main constituents of the atmosphere very cold planet. Also, there is observed the presence of small amounts of carbon monoxide, acetylene, nitrogen. It is assumed that the height of the atmospheric layer is around seven thousand kilometers. The hue of the planet is due to methane.

The sun from Uranus removed three billion kilometers – such a large distance does not allow the lights to warm up the planet. Even during the day, under direct sunlight, the surface temperature of Uranus is less than – 200°C. However, strangely, we already know winter and summer on the planet for decades and it would be logical to assume that in winter, the dark side of the planet temperature should be significantly lower. Here, however, scientists were surprised is the difference in «light» and «dark» sides of the Uranium is negligible. The range of temperature fluctuations of ±4° C. This means that it operates its own special ability to transfer heat from more heated areas to less heated.

On the coldest planet in the solar system blow strong winds of more than 550 km/h. Judging by pictures obtained from the Voyager, hurricanes planett are impermanent – calm-changing vortices and Vice versa.

Uranium

For comparison, the Earth receives from the Sun more heat than Uranium 400 times.
