It is worth mentioning that the earth also has its own second line of defense - the atmosphere. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info Meteorites without magnetic field enter

When it enters the atmosphere, it will be partially burned or exploded into small pieces, and the meteorite weighing several tons will be insignificant to the earth.

However, when the comet is at a certain distance from the Earth, the magnetic forces of the two come into play

The star will take a detour. As long as it goes in the slightest direction, the slightest mistake will occur.

A similar forecast is that Dr. Kenton of the United States accurately calculated that there were 100 percent

100 credibility, the moon will be divided into two halves in 1999 (a rare astronomical star of the Great Cross in the solar system), Dr. Kenton, although he has accurately calculated, may not have taken into account the magnetic force of the moon,

So contrary to the facts. The moon has not split in half, and it is uncertain whether comets and asteroids will collide with Earth

Material.

Meteorites can be described as uninvited guests to the earth, although people fear it and do not welcome it.

But when it's time to come, it will come. In terms of meteorite explosions, the destructive power of meteorites visiting the Earth is staggering. On June 30, 1960, an asteroid disintegrated over the forest, burning to pieces

Straight down, the 60-kilometer-radius Russian taiga forest suddenly burst into flames for a long time. At the beginning of January 1996, a 1 km diameter and 1 billion tons of extraterrestrial rocks were in the distance

At 3.6 million kilometers of the Earth, it is almost tangent to the Earth's orbit. If this stone hits the earth, it will wipe out most of the creatures on the earth, and the tilt of the sky will no longer be a cause for everyone.

Scientists have discovered 41 of various celestial bodies in the solar system with a diameter of more than 1 km

10,000, of which more than 30 will be tangent to the Earth's orbit. Astrophysicist Johnson, by precise calculations, believes that the one most likely to cause trouble for the Earth is the one named the "1983TB Devil".

The planet will visit the Earth in 2115, which is another astonishing prediction after the alarm of "comet hitting the Earth on August 21, 2119".

First discovered on October 11, 1983. The planet is currently orbiting the Sun and is getting closer to Earth. In 2115 A.D., it will be closer to the Earth than the Moon, and there is not enough data to add yet

to confirm whether it will collide directly with the Earth or simply pass by at that time. If it were to collide directly with the Earth, the force of its 80,000 miles per hour would be the force of its impact

, which is as harmful as hundreds of hydrogen bombs, will cause unimaginable disasters to the earth. The International Space Agency (IAA) has begun to carry out the work of "rejecting passengers".

There are two groups, one responsible for tracking and confirming extraterrestrial objects that may be tangent to Earth's orbit, and one responsible for driving them away from Earth's orbit.

There are 30 celestial bodies with diameters of more than 100 meters that could cause serious disasters to the Earth

10,000. The Hubble Astronomical Telescope, located at the geosynchronous orbit station, operates around the clock to confirm any anomalies. For hazards that are detected early and whose location is determined, space cannons can be used

A missile equipped with a conventional warhead is launched, and the thrust generated when the warhead explodes close to a dangerous object is used to deflect it away from its normal trajectory and away from the Earth. If it is less than 1, 500 million kilometers from the earth, it must be used

Nuclear warhead. The shock wave from a 1 million-ton explosive nuclear warhead can push an asteroid or comet 1.5 million kilometers from Earth out of its normal orbit.

The cost of saving the planet is not as astronomical as one might think

。 It costs about $60 million to install a telescope, and the annual operating cost is $12 million. As for the cost of eviction, some scholars suggest that nuclear warheads being dismantled by the United States and other countries could be used and as needed

It can be used with minor modifications.
