Mountain-Size_Asteroid_Flies_By_Earth-1f6a8d0840b4945c9ebf9e40bf0cd1deA huge asteroid will become the largest space rock of its kind to pass closest to Earth until 2027 today (Jan. 26) when it zooms safely by Earth beyond the orbit of the moon, and you can see the space rock’s flyby live online. The mountain-size asteroid 2004 BL86 will star in a live webcast at 11 a.m. EST (1600 GMT) by the online Slooh observatory and may even be visible to observers with binoculars or a small telescope because of its significant size – about a third of a mile wide. At its closest approach, the asteroid will be about 745,000 miles (1.2 million kilometers) from Earth and poses no danger of hitting our planet, according to NASA scientists. The Slooh webcast will be available free on at and feature live commentary from NASA near-Earth object expert Paul Chodas and NASA research scientist Lance Benner, and be hosted by Will Gater and Slooh astronomer Bob Berman.

This is going to be a show where you get it from the horse’s mouth.” More
