ELON MUSK has admitted that a devastating asteroid is coming to the planet and Earth currently has no defence in a bone-chilling tweet.

Space X CEO Elon Musk admitted Earth had no defence against impending asteroid threats as he responded to Express.co.uk's Apophis 'God of Chaos' asteroid story. NASA has already begun preparations for the arrival of asteroid 99942 Apophis - dubbed the 'God of Chaos' asteroid - which will skim past the earth in 10 years. The asteroid measures 340 meters across and will pass within just 19,000 miles of Earth's surface.  

Apophis is one of the largest asteroids to pass so close to the Earth's surface and a collision with the planet has the potential to be devastating for all life on Earth.

The billionaire CEO issued his chilling assessment after responding to friend Joe Rogan who shared the asteroid story from the Express.co.uk website.

Musk Tweeted: "Great name! Wouldn't worry about this particular one, but a big rock will hit Earth eventually and we currently have no defence."

However, NASA has taken steps towards studying and protecting Earth from asteroids it considers hazardous but currently has no protocols to defend against earth colliding space objects.
