The features of Uranus, the coldest planet in the solar system.
Uranus, the seventh planet from the Sun, is a member of the solar system, with a diameter of more than 51,000 km at the equator.
One of the great mysteries of Uranus is that it does not emit much heat.
Uranus is the coldest planet in the solar system, with an average temperature of -224 ° C.
All the planets in the universe emit the original heat left over from their composition, but Uranus seems to emit very little heat.
Astrologers and astronomers are trying to figure out why.
Uranus was discovered by William Herschel in Bath in 1781, but has so far been the only spacecraft to visit. It was Voyager 2, which flew by in 1986.
In the years since then, Scientists have looked at changes in Uranus and its atmosphere.
Although little was known about the weather from Voyager, recent observations on the ground revealed quite a few unusual weather systems.
Jupiter , Saturn , Uranus and Neptune are grouped together between the planets.
Uranus orbits the Sun 2.86 billion kilometers (1.78 billion miles).
A closer look reveals that Jupiter and Saturn are dominated by hydrogen and helium. Uranus and Neptune are made up of many rocks and ice.
They have more water and methane in their atmosphere, and their solids are larger.
Why is Uranus so cold?
Neptune is the coldest planet in our solar system, so it should be the coldest. So why is Uranus the coldest planet?
According to the study, it’s somehow suppresses the temperature in its atmosphere because it does not have large orbits like other planets.
Another is that Uranus may have lost most of its original heat earlier.
The unique feature of Uranus is that its axis tilts more than 97 ° to its orbit, so it rotates along the axis of its orbit.
It is estimated that Mars or some other size of Earth struck Uranus in the early part of the universe, causing it to lose much of its temperature.
Its massive tilt of the axis produces unique seasons for Uranus in its 84-year orbit around the Sun.
One axis receives 42 years of sunlight, and the other receives darkness. Then it took 42 years for the situation to reverse.
Due to this, the atmosphere is very strong and this is a situation we can not find anywhere else in the solar system.
When Voyager 2 flew over Uranus, only half of the planet shone brightly.
However, in 2007, While all the sun was shining from the equator, Uranus reached one of its equinoxes. This changes the dynamics of the atmosphere.
About the orbits of Uranus
The orbit of Uranus is similar to that of Jupiter. It is very different from what we find on Saturn and Neptune.
The rings are very dense and narrow curves, and they have changed since Voyager 2.
One of the rings is moving to Earth and new rings have been discovered.
It will take years to reach this distant ice world and investigate.
But if they did reach Uranus and Neptune, they would surely be able to solve some of their mysteries.
