An asteroid about the size of a bus shaved by Earth on Friday in what spacewatchers described as a "near-miss," though experts were not concerned about the possibility of an impact.
The asteroid, named 2012 BX34, measured between six and 19m in diameter, said Gareth Williams, associate director of the US-based Minor Planet Center which tracks space objects.
The asteroid, which had been unknown before it popped into view from a telescope in Arizona on Wednesday, came within about 60,000 km of Earth on Friday at about 1500 GMT, he said.
