Scientists warn of the dangers coming from space, Where there are planets threaten the earth because of the possibility of falling by on her.

The planets are considered a treasure of information for scientists,Where they reveal secrets of the solar anytime and history,Despite the wealth of information which may be granted by the small planets to scientists, but on the other hand, constitute a threat to life on earth, Scientists are seeking through the World Day of small planets to sensitize public opinion, political decision makers on this danger is rare, which might become disastrous.

The General Assembly of the United Nations announced last year on the 30th of June, the World Day of small planets in the same date, which was the largest asteroid hits Earth in modern history, that was on the 30th of June 1908,When a small planet  fell in the tonojosa  in Siberia and left wide destruction in an area of about 2,000 square kilometers,Making them almost unfit for human life.

The British Royal Astronomical Lord Martin Rees that the scientists know what the danger posed by asteroids, but he says that the recent scientific achievements with respect to remote sensing techniques to radically improve their ability to detect near-Earth objects and change the track. 

Although the scientists believe that the huge asteroids that threaten the Earth relatively rare, the comet, which fell in 2013 over the Russian city of chelyabinsk and caused the injury of 1200 people and damage to thousands of buildings, provided clear evidence of the possibility of the existence of dangerous objects in the solar system to be discovered and studied.

Scientists believe that the guilty are larger may erase the entire city, and prefer that represents about 1,700 near-earth asteroid potential danger. 

 The Foundation is also " 612" to a "guard" Space Telescope in 2018, which is the space telescope early warning infrared expects to discover about half million near-earth asteroid and its tracks.
