A hefty asteroid bigger than the Empire State Building is whizzing by the Earth this weekend.
It is classified by NASA as a 'Potentially Hazardous Asteroid' because of its relative proximity to Earth despite being quite a distance away.
The asteroid called 388945 (2008 TZ3) will fly past on Sunday, May 15 as part of its orbit around the sun which involves passing by the Earth every 732 days.
