An artist's concept of an asteroid approaching Earth.
Scientists at JPL were able to put together a list of upcoming encounters with our planet, and it goes on for decades into the future, and it turns out that in this relatively short period, the asteroid could fly by Earth for up to twenty-eight times. After its flyby on September 14, it is expected to pass by Earth not before October 19, 2038.
In just a few hours, the resulting giant fireball and shockwave spreads as far as Kansas, almost 4023km away from the initial impact.
An asteroid this big is comparable in size to St Paul's Cathedral in London or the Washington Monument in the US.
The billionaire issued this chilling assessment of our planetary defence capabilities after his friend Joe Rogan shared a story from a British newspaper which discussed how Nasa is preparing for the arrival of a space rock named after an Egyptian "God of Chaos" called Apophis.
They say the deadly rock's path around the sun means there are 100 "possible collisions between Apophis and the Earth, the most unsafe of them in 2068". Those which are predicted to have a minimum approach distance of less than 0.05 astronomical units and potentially measure more than 460 feet in diameter-like 2019 OU1-are deemed "potentially hazardous".
"Apophis has been one of those celestial bodies that has captured the public's interest since it was discovered in 2004", NASA's Steve Chesley said.
It was only spotted via a space telescope in Hawaii after it had sped by our planet, and could have caused chaos if it hit Earth. She is very enthusiastic in studying missions, launches, and discoveries of the space.
While the asteroid is not big enough to obliterate Earth, it could do some serious damage at the local level.
The massive rock, which has been estimated at 570m in diameter and bigger than New York's Empire State Building, has been classified as a "near-Earth object" (NEO). The asteroids are small rocky objects that orbit the sun.
