Apophis is just a planet with a diameter of 900 meters

The diameter of Apophis is about four hundred meters.

No, some people say that the end of the world in 2012 has not happened. Don't believe this kind of thing! ^_

The asteroid Apophis, the size of 63 buildings, will reach perigee tonight, about 14.5 million kilometers from Earth, only about 38 times the distance between the Earth and the Moon.

According to South Korea's "****", the Korean Astronomical Research Institute said that it is expected that "Apophis" will be close to 10,000 kilometers away from the Earth when it remeets the Earth on April 14, 2029.

Some scientists have even suggested that the planet could collide with Earth in April 2036. However, NASA denied this, saying that "the chance of a collision is very small."

China Broadcasting Network Beijing, February 15 (Reporter Fei Lei) According to the Voice of China's "News Vertical", there are encounters and hand-holding in romantic festivals, and there are also passing by, but missing is not always empty of regrets. Late this night, early tomorrow morning, an asteroid will pass by 10,000 kilometers from Earth. The near-Earth asteroid was named 2012da14 and is said to be the closest asteroid to Earth this century.

This is an asteroid with a mass of 130,000 tons and a diameter of 40 to 50 meters, don't look at it as the size of a building, but scientists warn that don't underestimate him, if it hits the earth, it will be enough to flatten the whole of London.

I don't think there was an asteroid hitting the Earth in 2013, and some people say that when the planet was only 24 kilometers above the earth, a mysterious object broke through the planet from behind the planet, and that it could be Ultraman Tiga, which is even more implausible, so NASA's news is wrong.

What are you afraid of destroying with missiles that's what Russia does.

You're talking about the near-Earth asteroid that poses the greatest threat to our planet so far.

The following paragraph of information is quoted from the Encyclopedia - "Apophis" entry Part 1 Apophis, the asteroid known to pose the greatest threat to Earth, with a maximum diameter of 394 meters; Once it hits the Earth, it will release 100,000 times more energy than the Hiroshima atomic bomb. According to experts' calculations, the "Apophis" asteroid will "pass by" the Earth in 2029; Hypothetical diagram of the Apophis asteroid meeting Earth.

Due to its orbit altered by the Earth's gravity, it will "return" to Earth in 2036 and is likely to hit the Earth with a 1 in 37 chance of colliding, the highest danger rating ever discovered among small celestial bodies. Of course, according to the latest calculations and data, this figure has dropped to about 1 in 250,000. More than 100 research groups around the world are working on the Apophis space mission, hoping to reduce or eliminate the possibility of a collision when it approaches Earth.

With a diameter of 320 meters, this is an asteroid.

Now you can hit it with a spaceship.

Scientists say humans are able to stop "unidentified objects" from hitting the Earth.

A few days ago, scientists from the US National Space Administration (NASA) discovered an unidentified object in space 13.5 million kilometers from the earth, and the probability of this unidentified object named 2000SG34 colliding with the earth reached 1,500. However, Chinese astronomers said that at present, human beings have the means to change the orbit of asteroids.

It is reported that 2000SG34 was discovered on September 29 by scientists from NASA's "Objects near Earth Research Program", it is about 29 to 69 meters long, and scientists have not yet been able to determine whether it is an asteroid or "space junk". However, according to orbital calculations, the probability of 2000SG34 hitting the Earth in 30 years is 1,500, which is far more than 100 times more than the probability of any object in space hitting the Earth.

Scientists say that if 2000SG34 were to be an asteroid and hit Earth, it would be as powerful as an atomic bomb of the same size. According to current estimates, it will make its closest approach to Earth on September 21, 2030. Since it is impossible to deduce a definite orbit, the possibility of hitting the Earth is certainly present.

Although the exact size and nature of 2000SG34 are yet to be further observed, due to its circular orbit around the Sun and the fact that it is in the same plane as the Sun, NASA scientists suspect that it is likely to be the waste of a man-made rocket, and if so, it would not pose any threat to Earth.

Astronomers say that 1,000 to 10,000 meteorites of all kinds hit the Earth every year, and that an asteroid of the size of 2,000SG34 is not scary, and only an asteroid with a diameter of more than 1 kilometer can cause a global effect, but an asteroid of this size hits the Earth only once every 100,000 years. At present, the total number of near-Earth asteroids with a diameter of more than 1 km is known to be around 900.

It's true, but the chance is only 1 in 360,000, and it was rumored to hit the earth by some **, which is completely taken out of context.

A group of international scientists**, the earth is facing a catastrophe. A meteorite called Apophis, which could hit Earth in April 2036, is so large that it is almost the size of the whole of England.

Astronomers, scientists and diplomats who recently met in San Francisco, USA, reminded us to remember to circle the lunar calendar on April 13, 2036, when Apophis will be very close to Earth. If you're lucky, it will pass by the earth; If you're unlucky, it's going to hit the Earth, and there's a 1 in 45,000 chance that it will hit the Earth head-on. Apophis, named after the mythical figure, is about 300 meters long, and if it were to hit him directly, any country or region would be destroyed, and the damage would be about the size of the whole of England.

Lu Jie, a Chinese-American astronaut, said the most feasible strategy would be to send a spacecraft to "lure away" Apophis, that is, send a gravitational pull to derail it, and the mission to save the planet is expected to cost $300 million. (Wang Peng).

Scientists have calculated it by calculation, but the comet has arrived.

It is also possible for the earth to deviate under the influence of external agents.

orbit, it is also possible that it will not hit the earth, I saw this **, it is this comet discovered by American scientists, and it is only possible, not absolute.

Everything is subject to change, or rather, our local dialect: "once you die, you will fall" which means that once you die, you will all die, and it's useless to be anxious, no, hehe.

Yes, there are several craters on Earth, how can there be craters without impact? And it should be a few hundred years from now that there is an intersection with the Earth's orbit, so there should be.

If human beings do not interfere, it will fly not far from the earth, and there is a 1 999999999 chance that it will collide with the earth, or it will be safe, how to say, just a chance!

The probability is about 1 500

And "it's very likely to be the waste of man-made rockets, and if that were the case, it wouldn't pose any threat to the planet."

In addition, even if it does hit, there is a way to stop it.

It's not because some people are willing to exaggerate the facts, like UFOs, scientists can't prove this event.

Meteorites often visit the Earth, but they vary in size.

A 50-meter meteorite hitting the Earth is a disaster!!

It's true, but the odds are small!

In 2036, the asteroid "Apophis" has a certain probability of hitting the Earth.

What is the probability that Apophis will hit the Earth? How do researchers get done? 1

Apophis, is a near-Earth asteroid. Nearly 200 initial observations (from June 19, 2004 to December 27, 2004) indicated that the asteroid would reach its closest position to the Earth's eastern hemisphere at 4:49 GMT+8 time on April 14, 2029, with a probability of colliding with the Earth at around 5:20 GMT+8 time of the day with a probability of 1 37 (. In the event of an impact, 6,400 trillion kilojoules of energy will be released, equivalent to the energy released by trillions of kilograms (100 million tons) of TNT explosives**.

The January 2013 observation report ruled out the full possibility of an impact by Annihilation in 2036 [1].

Yes, absolutely. It's better to hit to xx

The probability of impact is very small, one in a few thousand, but it is of course to pass by the earth, even if it hits the earth, human beings can launch the International Space Station to capture it to the earth, so that it is a "giant meteorite", so that human beings can use its resources to build cars, ships, airplanes, and various machines. If it is too late, simply launch a nuclear bomb to change its orbit so that it no longer passes through the Earth's orbit.

First of all, this asteroid is real, number 99942, and the English name is Apophis. In Egyptian mythology, apophis is the god of destruction and darkness, so its official Chinese name is translated as "Destruction Star". It is a near-Earth asteroid with a diameter of about 270 meters, and if it hits the Earth, it will release 25,000 times more energy than the Hiroshima atomic bomb.

When it was first discovered in 2004, due to the lack of observational data, there was still a large uncertainty in the calculation of the exact orbit of this asteroid, so at that time, the probability of it hitting the Earth in 2029 reached the highest, which was the highest risk of hitting the Earth on record. But subsequent observations have completely ruled out the possibility of a "Destroyer" hitting the Earth in 2029.

On April 13, 2029, which happens to be Black Friday, the asteroid will pass by Earth at least 29,470 kilometers away – a distance lower than the altitude of a geostationary satellite. An asteroid of this size grazing the Earth so close is statistically speaking, on average, only once every 800 years. At that time, the asteroid will be visible to the naked eye.

However, after a close flyby of Earth in 2029, Annistar will be affected by Earth's gravity and turn into another orbit. Current estimates suggest that the asteroid may orbit back to Earth again on April 13, 2036. Since the asteroid's orbit is still affected by some uncertainties, such as the interference of the Yarkovsky effect, it is currently impossible to determine the orbit of Anglomer in 2036.

As of October 7, 2009, the probability of astronomers** destroying God hitting Earth on April 13, 2036 is about 1,250,000.

But in 2013, astronomers had a good chance to revise the orbit of Reposacher with precision again. On January 9, the planet will pass by 14.45 million kilometers from Earth. Although the distance is still quite high, radars on the ground are already able to observe it and accurately measure its distance.

The observation is expected to dramatically improve the accuracy of the asteroid's orbit, with a high probability of completely ruling out the possibility of its impact on Earth in 2036.

At the very least, on NASA's Jet Propulsion Laboratory (JPL) official page, astronomers are quite optimistic that upcoming observations are likely to confirm that on April 13, 2036, the planet will be 49 million kilometers away from Earth.
