QQ47 Asteroid Threat To Earth was downgraded 7 years ago

In this Article – QQ47 Asteroid Threat To Earth was downgraded 7 years ago – we provide  the update from NASA in September 2003 and then following that is one of the many original news blurbs that indicated a potential earth impact by QQ47.

There has been a lot of talk on the web of the potential impact of this Asteroid in 2014. We believe that this is because people are reading the original 2003 impact threat article and not researching further and reporting that as fact when further analysis has revealed that there is no impact threat in 2014 just as the recent asteroid YU55 posed no threat when it passed between the earth and the moon on November 8, 2011.

Newly discovered asteroid 2003 QQ47 has received considerable media attention over the last few days because it had a small chance of colliding with the Earth in the year 2014 and was rated a "1" on the Torino impact hazard scale, which goes from 0 to 10. The odds of collision in 2014, as estimated by JPL's Sentry impact monitoring system, peaked at 1 chance in 250,000, a result which was posted on our Impact Risk Page on Saturday, August 30. Impact events at the Torino Scale 1 level certainly merit careful monitoring by astronomers, but these events do not warrant public concern. In fact, each year several newly discovered asteroids reach Torino Scale 1 for a brief period after discovery; 2003 QQ47 is the fourth such case this year.

As astronomers continue to monitor an asteroid and measure its position, more precise predictions can be made. On September 2, new measurements of QQ47's position allowed us to narrow our prediction of its path in 2014, and thus we could rule out any Earth impact possibilities for 2014. In our Impact Risk Page for 2003 QQ47, the entry for the year 2014 has now disappeared, although a number of potential impact events remain for later years. We expect that these too will be ruled out in the coming days as astronomers continue to track the object and we refine our orbit predictions.

These seemingly large day-to-day changes in impact predictions for newly discovered asteroids are just what we expect. In the few days after an asteroid is first discovered, its orbit is known only very approximately. The range of possible positions in future years is wide and can easily encompass the Earth, but as the object continues to be tracked, the range of possibilities shrinks quickly, allowing us to rule out any possibility of impact. This process is ongoing for 2003 QQ47, and could take days or even weeks before all potential impacts are ruled out.

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. T

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.
