"Death Star" will pass by the earth in ten years. Maybe one day it will become a reality that a planet collides with the earth. Will mankind face a crisis then?
According to reports, the near earth satellite, code name 99942, is also known as Apophis, commonly known as' star '. It will fly 19000 miles (30000 kilometers) away from the earth without direct impact. Nevertheless, its size and relative proximity to the earth are still a special moment for astronomers and scientists to abide by scientific knowledge and scientific system.
The blue dot is a satellite orbiting the earth.
"Approaching 2029 will be a great opportunity for science," said radar brozovich of JPL. The map of the United States also points out that it is quite rare for such a large object to pass Baidu cloud at such a close distance with the radius of the earth.
In 2013, a 20 meter diameter meteorite, phi; how to hit the sound effect earth, landed near Chelyabinsk state in Russia. Thousands of buildings were damaged and more than 1000 people were injured. Fortunately, no one died.
The "Star" will provide valuable information for scientists to abide by scientific knowledge and scientific system, and how to deal with more dangerous near earth objects in the future. "Apophis is currently known as about 2000 potential representatives," said zodas, head of NASA's near Earth Research Center. By observing its passage across the earth's radius in 2029, we will gain important scientific knowledge for defense one day. '
In April 2018, the 50 meter asteroid gear ratio calculation vehicle No. 2018ge3 passed the earth. It was 21 hours before astronomers discovered it.
Due to the problem of light, some of them are difficult to observe on the earth. Therefore, we are discussing the construction of a special space telescope forum, or the installation on the back of the moon, so as to explore the vast universe from multiple perspectives.
"We will use optical telescopes and radar to observe the asteroid," Zoe said. Through radar, we may be able to see some surface details. '
Death Star will pass the earth in ten years
According to foreign media reports, from April 29 to May 3 local time, 300 scientists, space engineers and other experts from the former governor of Maryland held a meeting on planetary gear ratio calculation defense mechanism, focusing on the dangers of small space to the earth and a variety of strategies.
Discussion strategy of astronomy experts from many countries
At the Defense Conference, the participants showed their magic power and applied magic methods, Liu Ye said. For example, NASA's planetary gear ratio calculation coordination office in Washington, D.C., and Johns Hopkins University's Applied Physics Laboratory (APL) jointly developed the dual star system small reorientation test system (DART). By 2022, it will be able to change the direction of 150 meters, so that it will no longer pose a threat to China.
According to the latest data released by NASA, a giant asteroid 'star' with a diameter of about 335 meters will be discovered in 2029. At that time, people will be able to see the light spots in the sky through the naked eye and see the 'Death Star'.
"We have to let people know that it's not a Hollywood blockbuster," NASA director Britten said at the opening ceremony. '
