o! Our distinguished guest is here. Does any of you know, Mr. Apophil?” What is the probability of a planet hitting the earth?”
Disturbed by Prime Minister Ismail’s voice, people greeted Han Xuan and Prince William individually, and then talked about the numbers they had heard. Some said it was 1 in 100, while others said Said one-fifty, which confused Han Xuan. He didn’t know who to believe.
This important news successfully attracted Han Xuan’s attention. After greeting others at the scene, he came to the place where he was still surrounded by people. Next to the big camel roasting on the blazing charcoal fire, I swallowed at the smell and took out my mobile phone to call the only familiar space madman Elon Musk.
The incident happened suddenly, regardless of what time it was in the United States. After the call was connected, he asked: “I just heard something about the asteroid that may hit the earth. Is it called Apophir or something?” , how much do you know about it?”
“It’s indeed called Apophil, little boss, have you heard the news too?
The TV station’s noon news program reported it. NASA has issued a level five danger alert. I just finished talking to my friends on the phone. , they told me that last week, a professor from MIT observed the threatening asteroid. After calculations, experts from various countries determined that it was very dangerous.
According to the report of the Hawaii Observatory, Apophil The asteroid is currently only about 0.05 astronomical units away from the earth, which is about 7.7 million kilometers.
If it continues to move forward at the current speed, it will reach the vicinity of the earth around 2006.
According to calculations, it is expected that it will have There is a probability of 1 in 380 that it will pass through the gravity keyhole above the earth and collide with the earth in seven years. The
current calculation error of the orbit is about 8,000 kilometers, and the authenticity of this data has yet to be determined Calculation, as it continues to get closer to the earth, the conclusion will be more accurate. “The
probability of one in 380 is already high enough that people cannot ignore its existence.”
The so-called “Earth’s gravity keyhole” refers to a relatively small special gravity area near the outside of the Earth, which can change the trajectory of an asteroid and may affect it and then impact the Earth.
/Han Xuan understands this common sense in astronomy. According to Musk, the planet should have passed by the Earth, but the gravity keyhole happened to be near the area it passed by, making the possibility of Apophir hitting the Earth. Greatly improve.
According to past experience, asteroids with a diameter of more than one kilometer will collide with the Earth every hundreds of thousands of years, and asteroids with a diameter of more than six kilometers will collide with the Earth every hundreds of millions of years. An impact of this level is enough to Cause a catastrophic disaster.
This time mankind is facing a big guy. Apophil’s siz
