There is one reality about Asteroid Threat that ultimately the Earth will be hit by one. According to the British astronomers, there is a 'slim' chance that a newly discovered asteroid -- 2003 QQ47 -- might hit Earth on March 21, 2014. Here is mentioned detailed information regarding huge Asteroid that might hit the earth in year of 2014.

When the day of Asteroid comes, there will be a sole factor that decides whether we stay alive or not and it is based on the size of the asteroid. The very biggest asteroids can eradicate all life on Earth. Medium objects of up to a kilometer can demolish continents. Small objects of only some meters diameter can wreck major cities.

The newly-discovered asteroid, called as 2003 QQ47, has a mass of about 2600 million tonnes and is 1.2 kilometers wide. If the asteroid hits our planet, the force would unleash of 350,000 megatonnes, which is approximately eight million times more dominant than the atomic bomb dropped over Hiroshima, Japan in 1945. It would be traveling at 75,000 miles an hour, or 20 miles a second on impact.

2003 QQ47 is significantly smaller than 2002 NT7 (2km), but has been identified as “an event meriting careful monitoring” by astronomers, who use the Torino scale to rate the chances of newly discovered asteroids and comets hitting the earth.

2003 QQ47 has been classified as a 1 on the Torino scale of impact hazards, discovered on August 24, 2003, by the Lincoln Near Earth Asteroid Research Project (an MIT Lincoln Laboratory program funded by the United States Air Force and NASA) in New Mexico. Scientists are urging calm, though, saying the odds of a disastrous collision are only about 1 in 909,000.

Asteroids like 2003 QQ47 are large piece of rock and debris left over from the formation of the solar system almost 5 billion years ago. Most are kept at a safe distance from the Earth in the asteroid belt among Mars and Jupiter. However, the gravitational influence of the gas massive planets such as Jupiter can nudge asteroids out of these safe orbits and send them plunging towards Earth.

Project manager for the UK NEO Information Centre, Kevin Yates, said: "As additional observations are made over the coming months, and the uncertainties decrease, asteroid 2003 QQ47 is likely to drop down the Torino scale.” The NEO Information Centre will keep on monitoring the newest results of observations and publishing regular updates on their website.
