The giant space rock, dubbed by NASA Asteroid 2019 CM4, will make a so-called “Earth Close Approach” next week. The asteroid will zip past the Earth on Monday, March 11, more than a month after it was discovered. NASA’s asteroid trackers have narrowed the flyby down to 6.12pm GMT (UTC). Asteroid CM4 was first spotted by NASA’s Jet Propulsion Laboratory (JPL) on February 8, this year.
The JPL estimates CM4 measures somewhere in the range of 223ft to 492ft (68m to 150m) in diameter.
Compared to a London double-decker bus, the asteroid could be up to 18-times longer.
Even at the lower end of the scale, the colossal asteroid is still 30-times longer than a Queen Size bed and nearly 17-times longer than a Volkswagen Beetle car.
With these terrifying dimensions in mind, the good news is NASA does not expect CM4 to crash into Earth any time soon.
