According to the US Space website, the world is alive! Please fasten your seat belt! In the late 1920s, the peak flight near the asteroid will be introduced. In two years, six asteroids will pass through Earth, but they will pose no threat to life on Earth. As of June 2027, six relatively large asteroids will sweep the Earth in two years.
On April 30, at the planetary defense conference of the International Aviation Society held at the University of Maryland, College Park, NASA's Lance Benner radar expert proposed data for future asteroids across the Earth. Analyze
Benner said: "The six asteroids will appear on Earth from the summer of 2027. At that time, they will be heavy news, but they will not collide with Earth to pose a threat. They will pass Earth for a short time, accompanied by Ao if they approach Earth, the two years will be very interesting. "
These orbital planes of asteroids do not cross the Earth's orbit, so there is no collision. But they are very close to Earth, allowing scientists to observe and analyze better, Benner points out that when they run into a perigee, they can see three asteroids with binoculars, one of which is called the Apophis. The asteroid can be seen with the naked eye.
One of the largest asteroids will pass over Earth as early as possible. It is called "1990 MU" and has a diameter of 2.8 kilometers. The proximity of two asteroids is even closer to Earth than the lunar orbit. During the six-asteroid flight near Earth, scientists will collect detailed radar observations of their asteroids, giving researchers a good opportunity to study the shape of asteroids and the speed of rotation.
In some cases, scientists will study these asteroids three times, providing enough data to analyze the subtle changes in the asteroid's operating speed when solar radiation is not uniform.
Scientists have realized the importance of asteroid exploration for many years, and spacecraft have begun to conduct asteroid exploration missions. For example, NASA's OSIRIS-Rex spacecraft and Japan's "Ostrich 2" spacecraft can approach rock asteroids. In the future, such space missions may detect subtle changes in the surface of the asteroid, which may be due to the asteroid's attraction to the asteroid.
As of 2027, the asteroids will be in close contact with the Earth at a rate twice a year, and finally the asteroid "Apophis" will pass through Earth. Benner said the six asteroids flew over the earth and even brought opportunities for the study of spacecraft orbits. On the same mission, they could carry research instruments to fly asteroids. I think this will cause great public interest in scientific exploration and may also cause interest in designing new spacecraft.
