The gargantuan space rock hurtling towards earth is bigger than the Eiffel Tower and named Apophis, after the Egyptian “God of Chaos”. It is on track to skim dangerously close to earth, about 19,000 miles (31,000 km) above the Earth’s surface. NASA said: “Current calculations show that Apophis still has a small chance of impacting Earth, less than 1 in 100,000 many decades from now.”
JPL astronomer Davide Farnocchia said in a blog post: “It is possible that there will be some surface changes, like small avalanches.”
News of the colossal space rock has caused a Twitterstorm with social media users over the world.
Some Twitter users expressed their fear of an impending collision between the asteroid and the earth.
Tweeter, Bislim Koci, said: “I am not kidding, this is my biggest fear. I got a lot of stress just reading that.”
One Twitter user said: “I swear if an asteroid actually hits the earth I will never let NASA hear the end of it.
“Not until they develop a defence actually capable of either destroying it or redirecting it.”
Another tweeted: “This is supposed to be a number one priority for the United Nation’s, investment to defend Earth from a giant asteroid.
“Every day gone by we are playing Russian roulette with an asteroid in space.”
Many Twitter users were in support of Mr Musk’s concerns over asteroid safety.
@read4liberty tweeted: “So @Elon, what’s your plan? You seem to be the only one doing something about sustainable life these days.”
Mr Musk suggests nuclear weapons should be set off on Mars to release its trapped carbon dioxide to make it habitable.
He believes once this happens humanity could move to the Red Planet to avoid any further asteroid dangers.
He Tweeted: “Not saying it solves everything, mind you, but it’s a step in the right direction.”
Many Twitter users were in support of Mr Musk’s plans to conquer Mars.
One Twitter used said: “If we can go to Mars we can build a defence against this thing.
“If we have the time then it’s just about resources.”
Another said: “Amen Elon. I fully endorse this.”
Others were not so keen in Mr Musk’s ideas to uproot Earth and the impracticably of nuking Mars.
A Twitter user, @Hoover, said: “No Elon, that sounds like a bad idea.”
Dr John Grohol said on Twitter: “It’s called extinction. It happens. You can’t prepare for once in a million year events.”
@Dimensionsmovie tweeted: “I feel like we might have more pressing things to worry about.”
Another Twitter user said: “We do not deserve to infest other planets until we can figure out to exist within our own resources here, harmoniously, together.”
