Ancestral asteroid impacts.

The Tunguska event in Siberia in 1908 that destroyed more than 3000 square kilometers of forest was caused, it is believed that by a fragment of a comet, although there are several theories on the subject, they also say that it could be an asteroid or a grazing asteroid, but the object in all the theories speak of a margin of between 50 to 150 meters in diameter.

Precisely on February 1, scientists from the University of Cincinnati in the USA announced that they had found evidence of an explosion of cosmic origin, in 11 archaeological sites of the Hopewell culture, a culture, an indigenous civilization that had developed in North America in a large area South of the Great Lakes, the event they have discovered occurred 1,500 years ago and left an imprint of an unusually high concentration of meteorites in a large layer of soil.

The researchers believe that the object was a comet that exploded in the atmosphere affecting an area of ​​almost 24,000 square kilometers, in the Ohio River Valley area, it was a disaster for the people who lived in that region and in fact there are some legends tribal that pick up an event that can fit perfectly with that of a comet entering the atmosphere and exploding.

You can imagine what it would mean today in an area as densely populated as ohio, which currently I think has 11 and a half million inhabitants, that's why it's important to know these issues, that's why it's important to investigate asteroids, comets and Have a plan.

The conclusion is that there are no asteroids larger than a kilometer, neither in 2027 nor in the next 100 or 200 years, but there is a risk of impact with smaller objects that can cause a lot of damage and therefore we must develop our planetary defense technology .
