Destroying the God Star, just by listening to the name, you know that this asteroid must not be a good stubble.
The ancient Egyptian deification of the god of darkness, chaos, and destruction was called "Apep", and its Greek name was "Apophis", the god of destruction, and the name of the star of destruction came from here. Why give an asteroid such a name? Because scientists once thought that it would hit the earth, which would bring devastating disaster to those of us living on the earth, and even scientists have calculated the specific date of its impact on the earth, that is, April 13, 2036. So how did this day come about? Why was the alarm for The Destruction of God to hit Earth later canceled?
The story begins on June 19, 2004, when three scientists found a spot of light in a comparison of digital images of the Kitt Peak National Observatory, and in some cases, this point of light showed a significant displacement.
Originally the asteroid had no name, but only a number, "2004 MN", an asteroid with a diameter of about 400 meters. In astronomy, the semi-main axis is less than an astronomical unit, and a near-Earth asteroid in Earth's orbit is called an "Ardenne-type asteroid", and 2004 MN is such an asteroid, and it has two intersections with the Earth's orbit. The real realization that the asteroid could hit Earth was on December 24, 2004, and after simulating the data collected from a large number of observation points, it was found that the probability of the asteroid hitting Earth in the future reached 1 in 233, and since then, as the number of observation point data has increased, this probability has begun to increase rapidly.
Later on December 24, the probability of a 2004 MN hitting Earth increased to 1 in 62.
Two days later, on December 27, 2004, after collecting data from 176 observation points for simulations, the probability of the asteroid hitting Earth increased to 1 in 37. But the asteroid hit Earth in a different way than we might think, it didn't crash straight up, but it needed Earth to pull it. According to calculations, April 13, 2029 is an important day, on this day, the asteroid will pass through the orbit of the geostationary satellite, and the position it passes through happens to be the position of the earth's gravitational keyhole, so its orbit will be affected by the earth's gravity and change, and this change in orbit will lay the groundwork for it to hit the earth in the future.
After orbiting for seven weeks, the orbit-altered Destroyer will crash into Earth, and the impact will be on April 13, 2036.
The news was immediately made public after the date of the impact was determined, and for the first time in history, it was determined that an asteroid would collide with The Earth, so the Global Observatory paid special attention to the asteroid, but as the observation point data increased, the probability of the asteroid hitting the Earth began to decline. On December 28, 2004, after simulating data from 139 observation points, it was found that the probability of the asteroid hitting the Earth was very small, and only on April 13, 2053, there was a slight possibility of colliding with the Earth, while the probability of collision with the Earth on other days was basically zero.
The indicator of the impact of negotius on the Earth is called the "Doolin Hazard Index", and on August 5, 2006, the Doolin Hazard Index of the asteroid called Destroyer finally dropped to zero, which means that the possibility of it hitting the Earth was completely eliminated, and everything was just a false alarm.
Although it is a false alarm, for astronomy enthusiasts, it means a feast. Although It will not hit Earth, it will happen in geostationary orbit on April 13, 2029, but the location it will cross will not pass through the gravitational keyhole. It would be only about 32,000 kilometers from Earth, which means that we only need to use a small telescope to see this asteroid with a diameter of only 400 meters, and it is rare for a person to catch such a chance once in a lifetime.
Now that the alarm for Theosoph to hit Earth has been lifted, but think about it a little bit, if this asteroid really hits the Earth, what kind of disaster will it bring to us?
The damage that an asteroid can cause when it hits Earth is closely related to the mass and speed of the asteroid. With a mass of about 4.6X10∧10 tons, and its relative speed with Earth is about 12.59 kilometers per second, such an asteroid if it hits Earth, the energy released is roughly equivalent to 2 billion tons of TNT equivalent. If you have no concept of TNT equivalents, it is simpler to say that this power is enough to directly destroy a city, but this is not the most terrible, the most terrible thing is the earthquake, tsunami and volcanic eruption after the impact, and the indirect damage caused by it is incalculable.
