It would not kill us the impact, but it is devastating effects
On Wednesday, the asteroid 2014 JO25 passed relatively close to Earth, but at a more than safe distance. Today is not a cause for concern, but even so, many do not stop wondering: what would happen if an asteroid hit the Earth?
According to Digital Trends, several researchers from the University of Southampton would kill us for the effects of the impact and not for the impact itself.
These are the seven deadly effects in case a meteorite hits Earth: earthquakes, tsunamis, collapse of debris, wind gusts, craters, high pressure and extreme temperatures. And of all these, they claim that the wind must be the most feared.
For the elaboration of this ranking, the scientists used a total of 50 thousand virtual simulations of impacts of meteorites in different parts of the planet. They took into account both those that disintegrate in the atmosphere into small pieces, and the larger rocks that would reach Earth.
Space agencies around the world constantly monitor the space to be aware of what surrounds us and possible collisions with these objects. NASA’s OSIRIS-REx mission aims to study the primitive asteroid Bennu – which bears the name of an Egyptian mythological bird associated with death, coincidence? No, Bennu is one of the 1,714 asteroids listed as potentially dangerous and is estimated to pass between Earth and Moon around 2135. This could disrupt its orbit and result in an impact by the end of the 22nd century.
Dante Lauretta, principal investigator of the mission and professor at the University of Arizona, said that this is a great motivation behind OSIRIS-REx, beyond solving the mystery of the creation of the Solar System. “These asteroids present an impact hazard, so we want to go there and understand their chemical and physical properties,” he explained to Chromium. After obtaining all the information, preventing a possible collision will no longer is their responsibility. “We are going to study in depth its composition and analyze its orbit in detail, so that future generations can solve the problem,” he added.
While Bennu is a known threat, there are many strangers out there. According to NASA found only half of Bennu-sized asteroids (about 500 meters in diameter) near Earth.
There are ideas to divert asteroids, says Lauretta, but will these ideas work in practice? We are more than a century from finding out.
