--Similar to the above text will often be seen in today's electronic publications, hopefully, as is usually the case, this is a meteor that will not have much impact on the earth, but this is not the case, Lucy's dream tells us that it will be an asteroid collision, the probability of such an asteroid collision with the earth is very small, about once in 60 million years, but it is this collision that has caused the extinction of dinosaurs and many other creatures 65 million years ago. www.biquge.info It has been a long time since then, according to the miscalculations of astronomers, this incident should have happened five million years ago, but due to various reasons, the asteroid did not arrive as scheduled, and it is because of this that the emergence of human beings has been possible, and today's earth civilization has been formed. We have lived too long, and we should be content. Professor Johnson gushed a lot.

"What are we going to do now?" Mary asked.

"Complete a written report and submit it to the Department of Aerospace of the League of Nations. In the meantime, the 'White Cloud Knight' should be told so that he and Lucy can further assist us in our work. If they can be warned, they will be able to find a solution. ”

Mary hung up a video call on the "White Cloud Knight", in fact, even if Mary didn't say anything, the "White Cloud Knight" understood what it meant, because his space lab had already observed the asteroid.

The asteroid comes from the star Centauri A at the edge of the Milky Way, the closest star system to the Solar System. The Centauri A galaxy is spinning at high speed like the solar system, and the asteroid, which was later named "R2", was ejected out of the vast interstellar space and into the solar system for no apparent reason. With the help of the asteroid belt between Jupiter and Mars, it approached Mars little by little, and was discovered by earthlings just as it flew past Mars and flew to Earth.

Planet R2 is 200 kilometers in diameter, weighs about 100 trillion tons, and is currently traveling at about 11 kilometers per second, hitting the Earth in about a month and a half. The "White Cloud Knight" ordered his men to stop all other research and devote all their energy to tracking the planet "R2".

Once this planet collides with the Earth, the consequences are extremely serious. Any meteorite of more than 100 kilograms hitting the earth is equivalent to a bombshell exploding at the World Trade Center, and the dust produced by the impact will cause serious pollution to the atmosphere, which may completely wipe out life within hundreds of square kilometers. The International Union Space Department also received the report on the same day, and they immediately ordered all their space astronomical stations and the Mars Space Launch Center to closely monitor the movements of the "R2" planet, and at the same time contacted the Galaxy Space Organization to request support. Professor Johnson, the "White Cloud Knight", Ling Xiao, Mary, Mike, and Lucy all gathered in the extremely large conference hall of the National League Space Department. The hole in the conference hall is flattened, like a flat galaxy, and the dense solar electric lights on the roof are like evenly distributed stars in the galaxy, flickering with a deep and distant light.

The matrix screen in the center of the conference hall shows the movement of planet "R2" at all times, and the radio interferometer observations of "White Cloud Knight" show that planet "R2" is rolling. What it will bring to the earth will be a catastrophe, it will be a destruction. As an ordinary scientist, Ling Xiao couldn't bear to let mankind suffer such a heavy calamity, but all this was inevitable. Professor Johnson suggested that the Department of Aerospace of the League of Nations temporarily block the news to avoid unnecessary confusion, and urged the "White Cloud Knight" and Lucy to come up with a solution as soon as possible to avoid this disaster。。。。。。
