Uranus is blue-green in color, as a result of the methane in its mostly hydrogen-helium atmosphere. Unlike the other planets of the solar system, Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star. This unusual orientation might be due to a collision with a planet-size body, or several small bodies, soon after it was formed.
A study suggested the colliding world could have been twice the size of Earth. This unusual tilt gives rise to extreme seasons that last for about 20 years. This means that for nearly a quarter of the Uranian year, which is equal to 84 Earth-years, the sun shines directly over each pole, leaving the other half of the planet to experience a long, dark and frigid winter. Uranus has the coldest atmosphere of any of the planets in the solar system, even though it is not the most distant from the sun.
That's because Uranus has little to no internal heat to supplement the heat from the sun. The magnetic poles of most planets are typically more or less lined up with the axis along which it rotates, but Uranus' magnetic field is tilted, with its magnetic axis tipped nearly 60 degrees away from the planet's axis of rotation.
This leads to a strangely lopsided magnetic field for Uranus, with the strength of the field at the northern hemisphere's surface being up to more than 10 times that of the strength at the southern hemisphere's surface. A study suggested the lopsided nature of Uranus' magnetic field may also lead it to flicker on and off during every rotation about every Uranus' atmospheric composition by volume is Its internal structure is made up of a mantle of water, ammonia and methane ices, as well as a core of iron and magnesium silicate.
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. A Question.

The planet is vast different from others because not only does it rotate in the opposite direction that most planets do, its equator is at a 97 degree angle to its orbit. The planet has an atmosphere of hydrogen and helium for the most part with a little bit of methane and some water and ammonia.
