NASA confirms that asteroid 2009 FF is heading towards Earth. The space rock is about 490 feet wide. It travels at 28,916 miles per hour. Scientists estimate it will pass Earth on 10 September. The asteroid’s closest distance will be 1,620,000 miles. Though vast, this distance is close by space standards. The asteroid belongs to the Aten group of space rocks. These objects are known for crossing Earth’s orbit. Despite its size, experts say it is harmless. NASA only considers objects hazardous under strict criteria. An asteroid must be closer than 7.4 million kilometres. It must also be wider than 85 metres. Asteroid 2009 FF does not meet either condition.
