An asteroid will make its closest pass by Earth at around 2:24 pm ET, flying about 17,200 miles above Earth's surface. It's estimated to be about 150 feet (45 meters) across with an estimated mass of 130,000 metric tons.
Experts say it won't hit the planet, but its flyby is the closest ever predicted for an object this large, according to NASA. The asteroid, called 2012 DA14, will fly between Earth and the satellites that ring the planet 22,200 miles up.

Asteroid 2012 DA14 has safely passed by Earth, according to NASA. The closest approach was 17,500 miles above Indonesia.
"It has passed closest approach and this asteroid is going away," said Paul Chodus of the Near Earth Object team. The asteroid is estimated to be about 150 feet (45 meters) across with an estimated mass of 130,000 metric tons. Its flyby was the closest ever for an object this large, according to NASA. Ref. CNN
Yes, I live in Indonesia, but I couldn't see anything. I don't know if such an object would be visible from the surface but is rainy season and the sky is almost always shrouded by clouds. Even the moon is not visible most of the nights.
The strange thing is that the media here didn't give any major importance to this fact so I knew it from the forums. Typical of local people: nothing is important until is too late.
A shame, we got a lot of coverage on the one in Russia but this one was way bigger and if it entered our atmosphere it would of likely took out a large city. Anyone wondering why we spend so much on space exploration should take a note of how vulnerable we are in the bigger universe.
You are absolutely right, XenoPhil. Some people consider a big waste investing in space exploration: not only in the US, in Europe is just the same. I remember how much criticism followed the American project of a space shield, which included the idea of deploying orbiting laser stations. Ok, that was focused on the rivalry with the Soviet Union and the fear of a nuclear attack but it would be a first step towards the creation of a planetary defense against incoming objects.
Experience tells us that many useful inventions came out of military research.
