As the calculations of scientists show, although there is a small one, the probability that the potentially dangerous near -earth asteroid Bennu will crash into the ground in 2182. Scientists have created a modeling that showed what consequences such a blow can lead to our planet. The study is published in the journal Science Advances, writes Live Science.

According to scientists, asteroid Benn has a width of about 500 meters and weighs about 74 million tons. This asteroid is the most potentially dangerous for our planet, which is approaching Earth every 6 years.

According to scientists, the asteroid’s blow will have catastrophic consequences for the entire planet, but the regions located next to the place of impact will be especially affected. Modeling showed that the more dangerous consequences of an asteroid strike will affect the climate of our planet and all humanity.

Although Benna is much less than a 10-kilometer asteroid, which destroyed dinosaurs about 66 million years ago, its fall can still lead to a sharp reduction in food production around the world and lead to a strong change in climate.

As a result of the strike of the Aststad, a huge crater is formed, and a strong shock wave will also arise, which will destroy everything at a distance of tens, and maybe hundreds of kilometers. The blow can also lead to a powerful earthquake or tsunami.

Modeling showed that after the fall of the asteroid into the atmosphere, from 100 to 400 million tons of dust will be thrown into the atmosphere. This dust will significantly reduce the amount of sunlight and heat that enters the ground. Thus, the global temperature of about 4 degrees Celsius will decrease sharply. This will also lead to a decrease in the amount of precipitation by about 15% and depletion of the ozone layer by about 30%.

Scientists say that sudden cooling will slow down plant growth on land, and will also lead to a reduction in photosynthesis by 30% in terrestrial and sea plants. Thus, this will jeopardize global food security. The authors of the study say that the global climate change can continue for 4 or more years after the fall of the asteroid.

At the same time, as the modeling showed, as a result of an asteroid’s blow, dusty dust, which will settle in oceans, can form and this provoke the heyday of some types of seaweed. Scientists believe that these algae can become an alternative to food production on land. But these same algae can seriously violate the balance of marine ecosystems.

The calculations of scientists show that despite the fact that Benna is the most potentially dangerous asteroid, the likelihood that it will crash in our planet after 157 years is 1 to 2700.

Now scientists believe that the asteroid Benn has broken off from a larger asteroid rich in carbon and water, about 2 billion - 700 million years ago. In 2023, the Osiris-Rex spacecraft delivered samples from this asteroid to Earth.

As Focus already wrote, according to a recent study, key components were found in the samples of asteroid Benn for creating life in the form in which we know it.

The focus also wrote that after 7 years a 60-meter asteroid and the chances of it can crash into the ground that he will happen higher than that of asteroid Benn.

Focus also wrote that the explosion of the SpaceX missile Ilona Mask could pollute the atmosphere and damage the ozone layer. Scientists believe that after a not entirely successful test flight of the Starship rocket in the atmosphere, a huge number of dangerous pollutants could form in the atmosphere.
