According to experts, if an asteroid is found between 5 and 10 years before the impact, it may deviate from its trajectory.
Although it seems unlikely Asteroid In the next hundred years, as the earth gets bigger, experts demand improvements Early detection The longer it takes to find the hazard, the more difficult it is to transfer the hazard.
Although it sends out a “calm” message due to “atypical” influences, Large asteroid, Spahr recalled that with current technology, only Fifty years prior to influences.
This concern was debated at the Planetary Defense Conference, where the Vienna-based United Nations Space Agency (UNOOSA) just held the meeting electronically.
This meeting simulated the 2021 PDC detected six months before the impact. This is a fictitious asteroid, 100 meters wide, Impact on the earth This will cause about 6 million deaths in Central Europe.
The opposite of the PDC simulation in 2021 is Apophis, which is a real asteroid with a width of 340 meters. Until March last year, people have been worried that it will collide with the PDC. land In 2068.
When it was discovered in 2004, there was a 10% probability that it would affect In 2029, But it was later stipulated that by that day it would pass approximately 31,000 kilometers from the earth.
Last februaryAsteroide is close enough to our planet for new orbit calculations.
As Luca Conversi, director of the ESA NEO Coordination Center of the European Space Agency, explained to EFE, it is now known that there is no danger when sailing in space. 2068 Back to land.
The so-called NEO (Near Earth Object) is more likely to be 50 million kilometers The distance to the earth is one third of the distance between our planet and the sun.
At present, the international community has found about 26,000 such objects, although only 1,000 have the possibility of any impact.
Usually, experts will rule out collisions of large asteroids, such as those that wiped out dinosaurs, for at least the next 100 years.
In the “risk list” of ESA and NASA, there is 2009 JF1, which is an asteroid about 13 meters that will pass through the Earth in 2022.
Even so, experts agree on the importance of not relaxing and improving the detection system, because, as their hypothesis indicates, asteroid impacts may also occur with a small reaction margin.
