It hits a small asteroid with the Earth
A small asteroid called 2008 TC3 small cuttlefish with the Earth yesterday, according to presented the scientist the NASA Tony Phillips. In agreement with calculations conducted by scientists of the jet propulsion laboratory of the NASA, the object I strike the Earth to the 9:46 hours of the 6 of October, time of the center of Mexico (2: 46 hours universal time of the 7 of October), on the sky of They sweat in Africa.
According to the astronomers the asteroid at the time of the average impact approximately 3 meters of diameter and I do not constitute a threat for the Earth, nevertheless produced a spectacular bolide in the sky, exploding with an energy equivalent to thousand kilograms of dynamite. The shocks with small asteroids are relatively frequent for the Earth, disintegrating themselves the majority of them with our planet, when friccionar with the atmosphere, occasionally some fragments of these bodies only manage to survive this, hitting itself with the terrestrial surface.
The first reports of the impact have arrived from the meteorological service of aviation of Norway, that they presented a great sparkle half an hour before the announced event, on the part of passengers who traveled in the neighborhoods of the site of the impact. The asteroid 2008 TC3, was shortage as soon as 6 of October the last, being the first asteroid in being observed before hitting the Earth. Its detection was possible thanks the use of a telescope in Arizona, within the program search of objects near the Earth.
A bolide is a type of very shining meteor whose mass is superior to about 10 grams or its magnitude or brightness is major that Venus or Jupiter. When entering the terrestrial atmosphere it originates a great wake that can be observed from several hundreds of kilometers of distance on the surface. It presents/displays the appearance of a fire sphere instead of an precise or stellar aspect. The track that leaves its step persists a time superior to the tens of seconds and can even get to be from several minutes and half an hour.
It arrives accompanied from acoustic phenomena as an explosion being able to sometimes find in the ground some fragments of the meteor that resist to the complete volatilisation to their passage by the atmosphere. Every year they penetrate in the atmosphere between 50 thousand and 100 thousand bolides.
