Asteroid Apophis to ram into Earth in 2036

Five-hundre-meter asteroid 2012 QG42 will fly Earth by next week. This 
celestial body is referred to the class of "potentially dangerous" asteroids. 
Astronomers try to conduct radar tests of the giant asteroid.

On September 14th, at 05:12 GMT (09:12 Moscow time) asteroid 2012 QG42 will fly 
at the distance of 0.019 AU - which is 2.84 million kilometers, or about 7.4 
average distances from planet Earth to the Moon.

In the future, this asteroid will fly even closer to Earth. On September 15, 
2039 it will fly at the distance of 0.014 AU (5.6 distance to the Moon), and on 
February 15, 2013 at 23:25 MSK -at  the distance of 26.9 thousand kilometers 
far from our planet. This distance is shorter than the height of the 
geostationary satellites.

One of the potentially disastrous asteroids for the Earth is Asteroid Apophis. 
According to NASA, the possible collision with Apophis, which may happen in 
2036, will produce 100 thousand times more energy than was produced as a result 
of the nuclear explosion in Hiroshima.

Asteroid 2004 VD17 is even more dangerous to our planet. It will cross the 
Earth's orbit on May 4, 2102. In June of this year, U.S. scientists proposed to 
use multiple solar-powered laser-equipped satellites to protect Earth from 
celestial bodies
