There is latest discovered asteroid 2003 QQ47 — might hit Earth about two-thirds of a mile wide could hit the earth on 21st March, 2014. But don’t lose your sleep because the chances of a collision are just 1 in 909,000, according to British astronomers. When that day comes a single factor will decide whether we survive or not and it is based on the Asteroid size. Small objects of only several metres width can destroy major cities. Medium objects of up to a kilometre can destroy continents. The very largest asteroids can destroy all life on Earth! If for instance a 2 kilometre asteroid were to hit the sea it would raise a tidal wave of unimaginable proportions – up to 10 kilometres high.
Asteroid “2003 QQ47” will be closely monitored over the next two months. If the event of it hitting Earth, the force would unleash of 350,000 megatons which is eight million times more powerful than the nuclear bomb that U.S. forces dropped on Hiroshima, Japan, during World War II. It would be traveling at 75,000 miles an hour with a mass of about 2,600 million.
The orbit of this asteroid has been calculated on only 51 observations during a seven-day period and needed further observations to determine if any danger does exist. 2003 QQ47 has been classified as a 1 on the Torino scale of impact hazards, revealed on August 24, 2003, by the Lincoln near Earth Asteroid Research Project in New Mexico.Almost 5 billion years ago, Asteroids like 2003 QQ47 are large piece of rock and wreckage left over from the formation of the solar system. Most of all asteroids are kept at a safe distance from the Earth.
