Scientists speculate that 4 billion years ago, a huge celestial body missed Uranus. Where did it go?

There are eight planets in the solar system, each of which has its own characteristics. They have their own orbit around the sun. The orbit of one of the planets is very strange. It is very different from the orbit of other planets, almost lying around the sun. This planet is Uranus.

Uranus is the seventh planet in the solar system from the inside out, and its volume ranks the third in the solar system. Although Uranus is far away from the earth, it was discovered as early as 1781 by human beings. The main reason why we can find this distant planet is that Uranus is bright, and it looks like a blue and light planet.

The reason why Uranus has this bright color is mainly due to its atmospheric composition and its surface is composed of water and ice. According to the survey, the main components of Uranus’s atmosphere are hydrogen, helium and methane. It is speculated that the interior may contain rich heavy elements. The mantle is made up of ice with methane and ammonia and may contain water. The core is made of ice and rock.

Uranus can be called an ice world, and it is also the coldest planet in the solar system. The lowest temperature is 224 degrees below zero, which is colder than Neptune. For Neptune, scientists are most concerned about its strange orbit, which is not a normal planetary orbit. What makes the orbit of Uranus like this?

Through research, scientists put forward a possibility: Uranus may have been hit by celestial bodies 4 billion years ago. Only the impact of celestial bodies can make Uranus’s orbit change greatly. Scientists speculate that the solar system is still in a state of chaos shortly after its formation, and collisions between celestial bodies often occur.

At that time, there was an extremely huge body, about twice the size of the earth, which hit Uranus, resulting in the orbit change of Uranus. You should know that Uranus is the leader of the solar system, no matter its volume or mass is not small. To make its orbit change, it must need an object with a large mass. Such an object absolutely reached the star level Don’t worry, even if a celestial body of the size and mass of earth collides with Uranus, it may not be able to shake it.

It can be seen that the celestial body that hit Uranus at that time must be much larger than the earth. It directly hit Uranus and deflected its orbit. So what kind of celestial body is this, and where does it go in the end? Scientists speculate that during the formation of the solar system, an object with rocks and ice hit Uranus.

For this reason, scientists have also simulated a variety of impact modes through computers. Through different modes and angles of impact, scientists believe that after the impact, the fragments of celestial bodies form a thin shell on the edge of the planet’s ice layer, which absorbs the heat from Uranus’s inner shell. This is probably the reason why the temperature of Uranus’s outer atmosphere is very low.

Although scientists speculate that a celestial body hit Uranus, there are still many doubts about the strange tilt angle of Uranus. As we said earlier, if we want to hit Uranus, the volume and mass of the celestial body should be twice that of the earth. But if such a celestial body hit Uranus head-on, why can its atmosphere be intact? This is not normal Li.

Scientists once again simulated the impact experiment by computer. This time, they did not let the celestial body hit Uranus head-on, but passed by. In the simulation experiment, they successfully deflected Uranus, tilted its angle, and preserved most of the atmosphere. So far, scientists have initially found the reason for the strange orbit of Uranus.

About 4 billion years ago, a celestial body about the size of Two Earths collided with Uranus. However, this kind of collision was not a full frontal collision. It was just a close brush that led to the tilt of Uranus’s orbit, resulting in the strange public transit. After understanding the reasons for the abnormal orbit of Uranus in the public orbit, some people may be more interested in the celestial body that hit Uranus.

What happened to the object that hit Uranus four billion years ago? You should know that its volume and mass are much larger than that of the earth. It doesn’t directly impact Uranus, but it just passes by. Although there will be losses, most of it will certainly remain. Where will it go in the end? If this object is found, does it represent a new planet?

In fact, scientists only speculate that the orbit of Uranus is caused by the impact of a huge celestial body. It is also unknown whether there is such a huge celestial body. If there really was a huge object passing by Uranus 4 billion years ago, it would most likely have entered the Kuiper belt at the edge of the solar system and become a planet in the solar system, perhaps the ninth largest planet that scientists have been looking for.

Scientists don’t know much about Uranus. We don’t have a special detector to detect Uranus. We may launch a Uranus detector in the near future. At that time, we will know more about it. Maybe we will have a new understanding of the cause of its abnormal orbit and reveal more secrets about Uranus.
