In another alarming reminder of our vulnerability to the big rocks falling from space, scientists found an asteroid chunk that hit the Earth with almost no warning.
The Meteorite is a piece of 2018 LA asteroid – has a small rock that illuminated the sky over Botswana in June after being detected hours before the impact.
This is the third time we detect an asteroid coming into contact with the Earth. Sky Survey, part of NASA's Planetary Defense Mission

The asteroid hit the Earth at 38,000 km / h and showed up a huge fireball in the sky over Botswana, Africa – 19 hours after Lindley Johnson, global defense officer at NASA headquarters, said: "This object was much smaller than what we are charged with detect and warn, "said Lindley Johnson, head of Planetary Defense at NASA headquarters
. to exercise our capabilities and give some confidence, our impact prediction models are adequate to meet the potential impact of a larger object.
"The discovery of the 2018 LA asteroid is only the third time that an asteroid has been discovered on an impact trajectory," said Paul Chodas, director of the Center for the Study of Near-Earth Objects of NASA
. It is also only the second time that the high probability of an impact was predicted well before the event itself.
