Nice of them to let us know just in time for it Bus-Size Asteroid to Give Earth Close Shave Friday.. A small asteroid will make an extremely close pass by Earth Friday (Jan. 27), coming much nearer than the moon, but the space rock poses no danger of impacting our planet, NASA scientists say. The newfound asteroid 2012 BX34, which is about the size of a city bus, will pass within 36,750 miles (59,044 kilometers) of Earth at about 10:30 a.m. EST (1530 GMT) Friday, astronomers with NASA's Asteroid Watch program announced via Twitter. The space rock is about 36 feet (11 meters) wide, making it much too small to pose a threat to Earth. "It wouldn't get through our atmosphere intact even if it dared to try," Asteroid Watch scientists tweeted today (Jan. 26). Asteroid Watch is based at NASA's Jet Propulsion Laboratory in Pasadena, Calif. Asteroid 2012 BX34 will zip by at a distance about 0.17 times that separating Earth and the moon. The moon orbits Earth at an average distance of about 240,000 miles (386,000 km).

This is way too close ! The article stated that they have found 911 out of the estimated 981 near earth objects . Its the other est. 70 they dont know about yet .
In this article I went deeper and checked out spaceweather.com and according to the article, be on the lookout jan. 28-29 for more aurora activity . It was cloudy here the other night but I did get a small glimpse of green when the clouds barely opened up a bit,,,bummer it was rainy here throughout most of the night. Go figure,,, tonight was clear and no aurora so far.

How can they estimate how many near earth objects there are if they haven't found them yet? There could be a zillion of them for all they know. That bus-sized asteroid might just be the leader of the pack.

Yep..how the devil can something so close to the earth not be tracked much earlier? Sheesh...I feel all warm and secure

Jo doesn't care what their excuse is...she thinks it's lame!

Skywalker thinks jo is right. It is a lame excuse. That was pretty close for an asteroid. In fact, that's probably the closest NEO that I have ever heard of. Kind of makes you wonder what else is lurking around out there that is "not a threat to us."

I would also like to know how a 36 foot chunk of iron can not possibly get through our atmosphere? When those satellites fall tiny little pieces of them manage to survive and satellites are not made out of solid iron. That thing must weigh a gazillion tons! How could it not get through the atmosphere?

News flash! The news does NOT tell you what you need to know. It does tell you too much about what you don't need to know - like the gurney taking the body to the ambulance, hysterical mother, etc. If that chunk had hit the earth at least some people would be inconvenienced - if not downright dead. If it hit the ocean it might have resulted in a wave that eventually hit some beach or other.

Of course not jo...they just misrepresented the facts.

How could it not get through the atmosphere? I totally agree and have been wondering the same thing ! If a satellite can make it through entry,,,so can a huge chunk of iron and nickel and whatever else these things are made of. I believe it depends on composition, angle of entry, and what not. As for them lying or misrepresenting the facts,,,,no,,, of course not

Goodness..they lied??? Ya don't say?!?! People on TV LIE?!?!?! REALLY?!?!?! I thought everyone on TV (especially the politicians and news anchors getting paid off by big corporations like GE) was an honest God fearing Christian!!!! OMG OMG OMG...

As for them lying or misrepresenting the facts,,,,no,,, of course not I'm sure speed/velocity also has something to do with it... Space rocks are probably traveling much faster than satellites... they have a longer time to accelerate towards the earth as well by being pulled by its gravity... you know the laws of physics... an object in motion tends to stay in motion until it's affected by another force like gravity... which can speed up, slow down, or change the object's trajectory... The faster an object is rocketing through space, the more friction will be caused when it enters the atmosphere of Earth... the more friction on the object... the more mass of it will burn off... ~shrug~

Man-made metals are also highly refined... they are melted together and smoothed without any air bubbles or pockets inside of them... most space rocks aren't that good... I'm sure a lot of them are porous... or "hollow" on the inside... and that causes them to break apart into smaller pieces... which burn up in the atmosphere due to friction much faster...

If you rub an uneven surface against your hand it will create more friction than a smooth surface...

yes..that's why just a bit of beard stubble is nice

I don't think beard stubble on a meteor the size of a bus would slow one of those suckers down.
