Asteroid 2014 YB35 will pass 2.8 million miles from Earth tomorrow . It was discovered by the Catalina Sky Survey at the University of Arizona . Nasa classifies it as a 'Potentially Hazardous Asteroid ' ( PHA ) , which means that if an object is large enough to cause damage or destruction on earth then we should be able to find out about its orbit and trajectory in space before it passes us.
Asteroid 2014 YB35 will pass 2.8 million miles from Earth tomorrow . It was discovered by the Catalina Sky Survey at the University of Arizona . Nasa classifies it as a 'Potentially Hazardous Asteroid ' ( PHA ) The asteroid is estimated to be 1,640 feet-wide ( 500 metres ) This would be large enough to cause devastation - but it will not hit Earth . In fact it will sail past at distance that is 11.7 times further than the distance between the Earth and the moon . Experts said , however , it highlights a need to do more to track asteroids .
