Asteroids Are Coming: Do You Know Where Your Children Are?
In fact, it is astéroïdo day happens Friday, June 30 and you want your children to pay attention. You too.
Really? As if climate change Brexit, Trump, North Korea, possible trade wars and all that was not enough, you have to worry about asteroids coming to the planet?
You are right. In fact, earlier this month, June 6, an Object Near Earth – NEO or as they are known – the size of a football field was as close to us as the Moon.
In April, another well-known JO25 2014 and about 2000 feet in diameter, the size of Gibraltar rock, approved by the planet at a relatively close distance of 1.1 million miles, approximately 4 1/2 times that of the Moon.
And as the asteroids approaching the ground several times a week, this was the largest since 2004.
These rocks – smaller and especially the parts of the formation of the universe (move their head around it) – are going to close several times a week and usually pose no threat to the Earth. On average, an asteroid the size of an automobile collides with Earth’s atmosphere every year, it burns in a spectacular fireball.
About 2 000 years ago, a football field asteroid hits the planet and damages.
There have been two major strikes in relatively recent times that show the power of the threat. More recently, on February 15, 2013, a 59-foot, 10,000-tonne meteor that moved around 40 by 000 mph exploded in a blinding flash 14 1/2 miles from Chelyabinsk, Russia. The people on the floor have felt their heat.
In the 20th century, the greatest known impact of human history was a meteorite or asteroid that exploded three to six miles above an area near the Tunguska River in Siberia, flattening about 770 square miles of forest. No human being hurt.
It was estimated between 200 and 620 feet in diameter. It is believed that energy equivalent to 1000 times that of the atomic bomb on Hiroshima fell.
Now consider this: attacking any meteor between 1 and 1 1/2 miles in diameter would have a global impact.
No more sweating? The meteor that hit the ground eventually erase dinosaurs and trigger mass extinctions, no more than six miles and has published about a billion times the energy of the Hiroshima bomb.

The Tunguska incident took place on June 30, 1908. This is why the founders of the Asteroid Day were established on the same date every year worldwide to illuminate the dangers NEO can present to a world that was not enough to Map the location of the millions of NEOs in our solar system that have the potential to hit the planet and even the destruction of a city.
Specifically, only 10 000 were found – only 1%. This explains the “100x Declaration” signed by 40,000 citizens, including 200 scientists and cultural personalities in the world, including a multitude of astronauts, Nobel laureates, facilitators and entrepreneurs.
