December 24, the eve of the feast of Christmas in the asteroid will fly near the ground called 2003 SD 220 employees of NASA assure us that we risk not end of the world, while noting, however, that any collision could cause a huge disaster.
The asteroid 2003 SD 220 fly past Earth at a distance of 10 million kilometers, which is 1/15 of the distance between our planet and the sun. The property is approximately 2.5 kilometers in diameter, and therefore the potential event would have been able to destroy the entire continent.
Therefore, employees of the US space agency for quite some time closely track the asteroid, following the trajectory of its flight. A team of scientists is preparing, among others, to carry out radar observation of an asteroid with the Arecibo Observatory in Puerto Rico. They will still be carried out from mid-December.
Radars are at the moment the most effective method of observation, with which you can evaluate the physical and dynamic characteristics of asteroids approaching the planet. With it, scientists can create three-dimensional models are in a potentially dangerous objects and evaluate their trajectory.
There is no shortage opinion that passage of the asteroid may have an impact on the Earth’s gravity, which would result in numerous earthquakes and volcanic eruptions. NASA employees, however, did not address this issue.
The asteroid 2003 SD 220 is on the list 17 potentially dangerous objects that might threaten Earth. NASA employees in spite of everything, however, remain calm. In their view, the risk of a collision with an object 2003 SD 220, which around Christmas is in the vicinity of Earth, is only 0.01 percent.
