The asteroid Apophis was discovered on June 9, 2004/kloc-0.
This is an asteroid weighing 26.99 billion kilograms, much larger than the Empire State Building.
On April 13, 2029, it will pass the shortest distance of about 30,000 kilometers from the Earth.
According to scientists' calculations, the probability of Apophis hitting the earth is 2.7%.
Considering the damage it may cause, this is very close.
If it hits the earth, its destructive power will exceed 1000 Hiroshima atomic bombs.
I hope it's just a rush and won't do any harm to human civilization.
