Double meteorite fly near Earth

On July 14, a double-sized meteorite approached the Earth. While not colliding with our planet, scientists warn it to show that the Earth is at risk from the universe.

Space.com said the double meteorite, consisting of two small meteorites with a diameter of 600m and 200m, called 2008 BT18 , flew about 2 million kilometers from Earth at the nearest distance, six times the distance from the Left. Land to the Moon. Lincoln's Near Earth Earth Meteorological Research Program (LINEAR) by the American Space Agency (NASA) and Massachusetts Institute of Technology (MIT) has discovered double meteorites since January 2008.

Although this time 2008 BT18 is not dangerous, but NASA still reviews 2008 BT18 is likely to cause disaster because scientists have not yet determined its flight trajectory in the future. NASA scientists say this is also an opportunity for astronomers to study more about double meteorites, because it is possible that one day a double meteorite will fly towards Earth. NASA said deflecting the double meteorite is a much more difficult task than dealing with a single meteorite. According to Space.com, about 15% of the meteorite near Earth is double meteorite.

The meteorite changes the trajectory is not rare. In 2029, an asteroid named Apophis will come very close to Earth and change its trajectory significantly due to Earth's attraction. It is likely that it will crash into our planet.
