A meteor that exploded in the skies above Russia's Ural Mountains was the largest since the Tunguska blast in Siberia in 1908 and released about 33 times the energy of the atomic bomb that destroyed Hiroshima.
Before hitting the Earth's atmosphere Friday, the object was about 17 meters (55 feet) and had a mass of about 10,000 tons, the U.S. National Aeronautics and Space Administration said in a statement.
The meteor, which hit 16 hours before an asteroid half the length of a football field hurtled past Earth, has prompted calls to be more vigilant about the risks of strikes from space. Every day, 100 tons of dust and sand-size particles enter the Earth's atmosphere, most of which burns up.

The fragments of the meterorite are very important to understand the past of our Solar System, because the meteorites
appeared at the same time as the planets and the sun, more than 4,5 billions years ago.
This happening is a proof that nowadays, as ever, we can´t control the universe and anything can happen.
