An asteroid between 11 to 34 meters across (36 to 111ft), roughly the size of 10 jumbo African elephants, made a remarkably close approach to Earth on Monday morning, passing by at a distance only half that of the Moon.

spot with a telescope. “This is moving very quickly, very nearby to us,” Eric Edelman, an astronomer with Slooh, said during a live broadcast of the surprise flyby at 7:47am ET on January 9. The near-Earth object, or NEO, has “a particularly elliptical orbit,” he noted, adding that “it actually crosses the orbits of two planets, Venus and Earth.” READ MORE
