....so this ISN'T the same meteor that is supposed to buzz the planet today? 2012 DA##? This is a DIFFERENT ONE? How did we not know this was going to happen?
I WANT ANSWERS!
Less than 1% of meteors are currently known (read that today in one of the stories).
I know you're joking around, but I thought it was interesting. There is also apparently a large "atomic bomb sized or larger" impact about every 1200 years (the last one being Tunguska in 1908, so hopefully we are fine for a while).
Although the same story said that ones equal to Tunguska could have happened more often and news just didn't get around, or the stories were not preserved.

It came from the direction of the sun as well. So it was obscured.

Plus they think it was only one meter in size which would make it very, very difficult to detect.
I think NASA is doing a great job at detecting them considering the limited funding they get. (The US military spends more on air conditioners then the entire NASA budget).
They have a really good idea on the all the planet killers. (like of the one that killed the dinos) We are safe for at least 100 years.
Smaller ones like the near miss that is going to happen later today could pop up with not too much warning. Those ones are not planet killers but could devastate a 2000 KM square area.

Do you think though, that if they did discover a planet killing or altering meteor heading towards Earth, that they would make the knowledge public? It's difficult to say.
It's worth noting that life has always survived, even if drastically altered.

Sure, the search is very public. They even enlist amateur astronomers to help them.
In terms of the discovery efforts for NEOs, NASA's current goal is to discover at least 90% of all NEOs whose diameters are larger than 1 kilometer within 10 years. To meet the NASA goal, the rate with which new objects are discovered will necessarily be largest in the first few years. This is because during the latter years of the 10-year interval, more and more "discoveries" will actually be of objects that have been previously found. Currently, the best estimate of the total population of NEOs larger than one kilometer is about 1000.

World governments may want to keep the knowledge secret but there is no way the scientists would be able to.

So... you're saying that it's going to hit.

They discover asteroids that barely missed earth after the fact all of the time. You could very well wake up tomorrow and find out that there is a big one that will hit us in a matter of months. The sky is awfully big.
I love that with the smart phones (and Russian dash cams) of today, if something like this happens in a populated area we get nice clear video from 700 different angles complete with sound.
15-20 years ago we'd read about this tomorrow in the newspaper.
