An asteroid the size of a city set to enter Earth’s orbit on Thursday

The asteroid, known officially as Asteroid 2014 QJ33 will fly-by Earth on September 17 travelling at a speed of 19,371 miles per hour. That’s 8.66 kilometres a second!
Nasa is tracking the asteroid which is predicted to be 48m to 110m, or 157 to 360 feet, wide – which could mean it is bigger than London Bridge!
But there is nothing to worry about – it will pass by our planet at a safe distance – precisely 1,592,819 miles away from Earth.Asteroids are giant space rocks in our solar system that orbit the Sun.
Sometimes they are called NEOs – Near Earth Objects.
