A new look at the 111-year-old asteroid hit provides clues to future effects



Scientists reexamined the secrets of a 1908 asteroid impact to better understand the likelihood of these events in the future In Siberia, researchers developed computer modules with over 500 million combinations of asteroid and entry features that, according to a statement by NASA Profile like the Tunguska crash.

The researchers found that these medium-sized asteroids may have a reach Earth with frequencies on a scale measured in millennia rather than centuries, as scientists previously believed, the statement added.

At the time, the impact was reported in the media as a possible volcanic explosion or as a mining accident, before the researchers concluded that it was caused by a massive object colliding with Earth.

"It's also Characteristic of the Type of Impact That We Are" David Morrison, planetarist at NASA's Ames Research Center in California, said in the statement that he probably needs to protect himself from this in the future.

The asteroid was not large enough to cause mass extinction on Earth, but it was a medium-sized rock that made it through the atmosphere and seriously affected a limited area.

"Because there are so few cases observed, there remains a lot of uncertainty about how large the asteroids are in the atmosphere and how much damage they can do to the ground," said Lorien Researcher, Amiens Researcher, NASA Asteroid Threat Assessment project, said in the statement.

Among the computer models, the one most similar to the Tunguska asteroid was a rocky body between 1

64 and 262 feet (50 to 80 meters) wide that reached the atmosphere at approximately 55,000 km / h. According to NASA, the deposition of energy corresponds to an explosion of 10 to 30 megatons.

However, according to scientists' estimates of the asteroids on Earth, the calculations are good news. This is because the mathematics used suggests that the interval between the occurrence of these effects would be about one millennium.

The research is described in an article published in the journal Icarus next month.
