Asteroids of space origin capable of causing massive extinctions have hit the Earth on average every 50 to 60 million years. The dinosaurs were certainly killed 66 million years ago by an asteroid striking the Gulf of Mexico. An expert has now evoked the possibility that another asteroid exists capable of creating an impact likely to destroy our entire planet.
Dr. Lewis Dartnell, professor of science communication at the University of Westminster, assured Mashable India that no asteroid would destroy the entire world.
He said, "Earth will not be destroyed by an asteroid.
"All right, a different question could be, could all life on Earth be brought to extinction by asteroids?
"Again, the answer would be no. There is no asteroid big enough for a collision with the Earth to do. "
The NASA space agency estimates 796,751 the current number of asteroids.

Most of these rubbish are in orbit around the sun between Mars and Jupiter in the main asteroid belt.
The size of these ancient space rocks ranges from Vesta – the largest at 530 km in diameter – to bodies less than 10 meters in diameter.
Dr. Dartnell added that it was highly unlikely that an asteroid armageddon would occur in the near future.
He said: "If we were very, very unlucky and they hit a big city, they could destroy it.

"But, the chances of that happening are very unlikely."
"The asteroid Apophis is one of the asteroids that we monitor and we know that it will not have an impact for the next decades and that it will continue on the track."
The asteroid expert has nevertheless conducted many researches on the restart of civilization after an apocalypse event.
And he thinks that the post-apocalypse survival skills of recent generations have regressed.
He said: "The scenes of how the modern world works – where are all the things you take for everyday life gained – whether it's the food that appears on the store shelves, the electricity or the tools we use or the cities in which we live … do they provide us?
"How are they made? How does it come to us?
"Our grandparents had a much closer connection with these things, they understood where it came from and how they were made.
"I think these skills have been lost in the most recent generations.
"We do not understand or really appreciate where they come from."
