Each day about 50 tons of rock material from space land on the surface of the Earth. They are small pieces, shooting stars, but with those little rocks there are up to 100,000 hazardous asteroids and meteorites identified within a hundred yards and more than 1,000 km away. The impact of one of them against the earth’s crust could cause significant damage, if not the extinction of the human race.
The last space happened yesterday fireball ‘near’ the planet, at a distance of 40,000 kilometers over the skies of New Zealand. It is the asteroid ‘RC 2014′, about 20 meters in diameter, which had been discovered only seven days earlier.
But it was not the only visit of the day. According to the Research Network Fireballs and Meteorites, 6.56 hours on a bright fireball surprised the inhabitants of the provinces of Barcelona and Tarragona. The phenomenon was captured by numerous citizens who hung the pictures on social networks.
Asteroids are rocky bodies that came together to form a planet, and to be splitting as they fiving each other. Meteorites are remnants of tails of comets and small asteroids.
While some scientists say, for the moment, there is minimal risk of a meteor collision with Earth, other research could be intercepted as a trajectory that threatened Earth or included, the destruction of the rock space. Experts believe that there is that “fear them”, since you can predict its path. Another thing is how to cope with today’s technology.
And the only direct impact of an asteroid about 80 meters in diameter hit the Earth would release approximately 2.5 megatons of energy and produce a crater a mile, similar to which produced another space rock 50,000 years ago in the desert of Arizona (USA). If it is precipitated on the sea cause a large tsunami.
