The US space agency Nasa expects Asteroid 388945 (2008 TZ3) to pass Earth at around 5.18pm ET and 9.18pm GMT.
The giant space rock is predicted to be up to 1,608 feet wide. By comparison, New York’s Empire State Building stands at 1,454 feet tall.
Although Asteroid 388945 should pass us from a distance of about 3.5million miles away, it is still considered a possible threat.
If an asteroid comes within 4.65million miles of our planet and is over a certain size, it’s considered “potentially hazardous” by cautious space agencies.
