Asteroid projurio pored Zemlje

[Alexdelarge]

Asteroid veličine onog koji je pre jednog veka udario u Sibir projurio je pored Zemlje, saopštila je američka svemirska agencija NASA.

NASA je objavila da je asteroid nazvan 2009 DD45 "prozujao" u ponedeljak ujutru na udaljenosti od 78.500 kilometara od Zemlje. To je svega duplo veća udaljenost od one na kojoj se nalaze neki telekomunikacioni sateliti i oko petine udaljenosti Meseca.

Ta "svemirska lopta" bila je prečnika između 21 i 47 metara, kako su naveli naučnici iz NASA, koji su dodali da je iste veličine bio i asteroid koji je 1908. udario u Sibir i sravnio sa zemljom više od 2.070 kvadratnih kilometara šuma.

Naučnici su spazili asteroid tek dva dana pre njegovog prolaska, a najbliži Zemlji je bio iznad Tihog okeana, nedaleko od Tahitija.

pa dobro, majku im božju, šta ti naučnici rade?
jel ih zato plaćamo, da sviraju kurcu, il da paze na to nebo?
zar nije još hauard hox reko pre pola veka. KEEP WATCHING THAT GOD DAMNED SKY!

a oni, 2 dana pred apokalipsu....

eeee, gde su brus vilis i ben aflek kad su nam najpotrebniji!?

According to NASA's NEO program 2009 DD45 is a sizable rock, between 21 and 47 meters in diameter.  This is comparable to the size of the Tunguska impactor of 1908. Since the object is in a solar orbit that touches on Earth's orbit, astronomers predict that that 2009 will visit us again in future years.

a oni, 2 dana pred apokalipsu....
 

a meni je uvek u filmovima najgore kad kao sve je super, i onda odjednom neki amerikanac otkrije da ce za 2 dana ili za 30 dana da nastupi ledeno doba ili da dojuri asteroid katastrofalne velicine, i bice smak sveta. a ja kao "ma daaaaaaj, kao niko nije primetio ranije, bas!!". eto ti sad, vidis da ima istine cak i u tim filmovima.

Ovo je bolja priča: Dva dana posle apokalipse saznamo da se dogodila...

Cudno je da Sinak nije imao ovu informaciju.

Izdala ga bolest. Postao je racionalan i samosvestan. Utopice se u gomilu. U sivilo prosecnosti.

Giant Asteroid Hurtling To Earth: Could Lead To Human Extinction                    
Doduše, tek za osamsto i kusur godinica... Ako ste planirali da začnete dugotrajnu lozu potomaka, ju mej uont tu rikonsidr. Zanimljiva je ovde i opaska o "negativnoj gravitaciji"-

Stop what you’re doing, because human life as we know it could be about to come to an end. Or maybe it’s not. Either way, a giant asteroid is currently on a collision course with Earth, and if it hits then it could wipe out the planet.

If that’s enough to get your attention, then the fact that Asteroid 1950 DA apparently measures at 1,000 metres in diameter and could collide with Earth at around 40,000 miles per hour probably doesn’t bother you too.
According to the Daily Star, if the asteroid does hit our planet then it will cause such a huge explosion that “huge tsunamis capable of covering entire cities” will be triggered too. It’s also been revealed that the apocalyptic rock is traveling so fast at the moment that it is experiencing “negative gravity.”
Scientists have revealed that they regard any asteroid that measures in excess of 50 metres as a “city-killer,” so the fact that this one is 20 times the size of this warning has them increasingly alarmed. Another issue is that experts believe that it should have split up by now, but it is actually being held together by forces known as van der Waals.
A researcher from the University of Tennessee, Ben Rozitis has explained: “We found that 1950 DA is rotating faster than the break-up limit for its density. So if just gravity were holding this rubble pile together it would fly apart. Following the February 2013 asteroid impact in Russia there is renewed interest in figuring out how to deal with the potential hazard of an asteroid impact.”
He then added, “Understanding what holds these asteroids together can inform strategies to guard against future impact.”
However, those of you who have already started to build bomb-shelters and are beginning to pick which of their favorite friends and children will actually make it into their carefully structured, protective abode should probably cease their worrying because early predictions are that the asteroid will only strike Earth on March 16, 2880.
Odds that it will hit us on that date are currently at 300/1, while Charles Bolden, who is the chief at NASA, has admitted that the best defense against asteroids is prayer.
For the uninitiated, around 66 million years ago a huge asteroid collided with Earth in Mexico, and this led to the death of the dinosaurs as well as all of our plant life. This turned out to be good news for humans though, because a couple of million years later we profited from the demise of the T-Rex et al to become the dominant species of the planet.
