Has NASA confirmed the collision with Asteroid 2012 DA14 at February 15, 2013?, page 1

A few days ago- on February 23, 2013 was opened a new asteroid 2012 DA14, which, according to specialists of NASA- on February 15, 2013 will fly at a very short distance from the Earth - only 27,000 kilometers (see the photo of NASA website at the top of this article). According to scientists, asteroid 2012 DA14 has a length of 100 meters and in the case of hitting the Earth, can be released the energy, which equivalent to the explosion of the hydrogen bomb.

UPDATE UPDATE! Another more detailed article from Moscow, Russia I just found! en.rian.ru...

An asteroid of the same class as one that allegedly detonated over Tunguska River in 1908 will pass by Earth next year, flying closer than some man-made satellites, according to NASA.

The asteroid, 2012 DA14, will miss the planet by 26,900 kilometers on February 15, 2013, which is closer than satellites in the geostationary orbit of 35,700 kilometers, according to data on NASA’s website published Sunday.

The asteroid, first detected by the Spanish Observatorio Astronomico de La Sagra, is between 40 and 95 meters in diameter and belongs to Apollo group of near-Earth asteroids, many of which are potential collision hazards.

According to a quick google search, above 25 meters could be a real problem, so 4 times that at 100m (think in swimming pool lengths) is actually quite a large rock!

A 100 meter asteroid is not just going to burn up. How much damage it does depends on if it reaches the ground in one piece.

I read that this meteor can cause the same damage of an hydrogen bomb, or like the Tunguska Explosion. Put that on a major city and you have millions of dead people.
Did someone notice the date IS FEBRUARY 23 2013? This is the real end date of Timewave Zero.

Its only 100 meters across, short of it hitting a city or population centre can it really do that much damage? Suppose it depends on how fast its going and what its made of eh?

Based on its velocity relative to Earth and its estimated mass, it would deliver about 3 megatons of energy, comparable to a small hydrogen bomb. This is actually good news, as the Earth is mostly uninhabited. (It just seems crowded because most people live in cities.) It is not a planet killer. Now for the bad news. It is an Earth hugging Apollo family member with a period of 366 days. I might as well be the first to post this:

We can look forward to a close encounter every year from now until the end of its career. I might also as well be the first to point out that "DA" is Russian for "yes." Have fun!

I followed your link, and I am now in the year 2025, and that rock is getting away from a collision point as time goes by.

But it will be close next year!

Do you really think 100m of 'rock' would all burn up in the atmosphere? 27,000Km is very close (relatively speaking)

If you do want to guess at composition, impact angle, and velocity, this site would be helpful in estimating damage.
