An asteroid the size of football field will buzz past Earth
on 15th February, near our dear planet. It will not hit our Earth, but if the
case was something like this to happen, what would it look? An impact like this
would leave such a big crater, size of Washington. Scientist are pretty sure, that something like this would
happen, because a similar size asteroid made impact with Earth in 1908. A
meteorite weighing 100 million pounds entered the Earth’s atmosphere over
Tunguska in Siberia, burning up the sky and releasing the same amount of energy
which would possess 185 nuclear bombs dropped on Hiroshima.
Fortunately this meteorite hit the place on Earth where
there’s no population. You can imagine that a lot of animals had died and trees
were burned, but no human were harmed. This meteorite with a diameter of 40
meters, the meteorite is similar to the 2012 meteorite DA14 which will pass by
Earth at a distance of 27,000 kilometers. This is the closest passing by
recorded so far. This passage is not close enough to threaten Earth, although
it will pass by the area in which there are satellites that orbit around our
planet. Siberia was not that lucky in 1908.
Somewhere after 7 am on Jun 30, 1908 a man was sitting on
his chair in front of his store in Vanvara,
Russia when he
was suddenly thrown out of his chair. In the sky appeared a fiery rift, as the
man said later to scientists. Although located 64km away from the point of
impact, the man felt so much heat that he thought his shirt caught fire,
according to NASA scientists. Other witnesses have described they heard the
sounds of a blast of artillery fire.
Tunguska meteorite has
entered in the atmosphere at a speed of 53,900 km / h. There was no impact
crater because the pressure and heat of this entry made the space rocks
explode. The explosion leveled everything within 1287 square kilometers. By the time this asteroid hit Tunguska,
scientist thought that the impacts are similar to the nuclear bombs. However,
the explosion spread in all directions, while the objects in the universe carry
their energy in a single direction.
Asteroid 2012 DA14, space rock that will pass by Earth on
Friday will not threaten mankind. However, if that were to happen, the damage
would be tremendous. These strikes, are estimated to occur on Earth every few
thousand years. But because the comet disintegrating in the air and doesn’t
leave behind a crater, their traces is difficult to see – at the site of impact
in Tunguska is now only possible to see the
trees which grew back.
