NASA asteroid tracker: Look out as 19,300MPH asteroid skims the Earth TOMORROW

At the upper stage of NASA’s estimate, the asteroid is about four times as long as a London double-decker bus.

Towards the lower end of NASA’s scale, Asteroid FF is about 3.6 times longer than a Volkswagen Beetle car.

After the asteroid swings past our planet on Saturday, the space rock will cross paths with Earth again on October 9, 2022, and March 19, 2023.

The asteroid will then pass Venus on September 24, 2026.
