(UTV|USA) -Two satellites hurtling across the sky at nearly 33,000 mph (53,000 km/h) narrowly missed a collision over the US state of Pennsylvania on Wednesday.
The two object “crossed paths without incident,” a spokesman for US Space Command told the AFP news agency.
The satellites passed each other at 18:39 EST (23:39 GMT) some 550 miles (900km) above Pittsburgh.
The last time a major satellite collision occurred was in 2009.
Experts predicted that the satellites could pass within 40ft (12m) of each other. They are not operational, but it was feared a collision could create pieces of debris that would damage other objects in orbit.
