It is easy to forget Uranus. They are doves, in fact, in fourth place on the most massive planets in the solar system, but it is far from us.
Uranus walks in an alley three miles from the sun, and a sun turn, a year Uranus, takes 84 years-earth. In comparison, we are about 150 million miles from the sun.
But Uranus has strange characteristics like the planet. Among other things, the planet is almost entirely on the side, so the north and south poles of the planet are almost in line with what had been the equator. It revolves around its own axis, like the other planets, but it makes it wavy on the side.
To become more technical, Uranus has an extreme inclination of the axis of 97.8 degrees. The land has a slope of about 23.4 degrees, which is one of the reasons we have seasons, of which you can read more in this case.
Below you can see a pattern of how Uranus looks like earth. Note that the poles are in front of us, so the whole planet is put on the page:

Uranus radiates also very
These sniffles, and several other signs, may mean that Uranus was struck by something very big once in the distant past.

This is a theory that has been debated for several years, and now several NASA researchers have taken on the task of studying the theory by making a model of Uranus data, in order to make simulations of this giant collision. ] A shell
The force of the collision may have been large enough to beat Uranus to the side. This strange lack of radiant heat can also be explained by a collision.
The idea is that the mass and energy of the collision were large enough that the collision created a kind of shell around the Uranus core. The shell holds heat, according to the theory, and explains why Uranus is as cold as it is.
These theories confirm the researchers after running the simulations in the model. They tested many different conditions, but found crazy numbers.
For Uranus to have overturned and formed this inner shell, the planet or mass that collided with Uranus had to have a lot about twice as large as
Here you can see the simulation:
This is a number too large to print, but it is about 12 (with 24 zeros at the back) kilo. 19659021] Kaos
The object must have cut Uranus, as you can see in the simulation above. Scientists do not know what happened to Uranus, but it was probably a rocky planet.
If that happened as scientists believe, this dramatic event took place over four billion years ago. Then the solar system was young and it was not organized in a way as beautiful and painful as it seems today.
It was more chaotic and there was a greater chance of collision with other things in the solar system. A theory about how our own moon was created means that a Mars-sized planet slammed into the young earth about 4.5 billion years ago. The moon was then formed by the remains of this collision
