An unusual space body with parameters similar to a man-made object will approach Earth on Wednesday at a distance about three times less than the moon's orbit.
The object, named 2010 AL30, will fly by Earth at a distance of at least 128,000 km (about 80,000 miles) at 12:48 GMT. As it is some 10-15 meters long, there is no chance it will directly impact the planet.
