The American website appraisal 580000 asteroids

The distant asteroids actually very valuable and maybe it is richer than a country (D3 Gold). The United States has a website known asteroids contain more of the assessment of the mineral resource, including the value of an asteroid was as high as nearly trillions of dollars, as the one year of GDP. The reposted said mining the resource on the asteroid is not fiction. There is a website appraisal the asteroids, the highest valuation of the asteroid, called "241 Germanic Virginia", the asteroid is about 160 kilometers in diameter, it mainly with hydrocarbons of mineral resources total prices as high as $95.8 trillion. But in 2011, the global GDP also however is 70 trillion dollars. However, the scientists say, the asteroid is too far away from earth, about 345 million kilometers, the mining up very difficult. According to NASA's experience, from space back to about 60 grams of mineral cost as much as 1 billion dollars and the earth the same weight the price of gold but 3200 dollars. The "241 Germanic Virginia" is very difficult to exploit. It seems that the more rare things the more difficult. There are so many asteroids that mean there are so many sources wait us to exploit.
