Asteroid-665x385An asteroid is heading this way, and it’s a big one. OK, so asteroids are always heading this way. But this particular asteroid, lovingly named 2004 BL86 by people who get paid to come up with such names, is remarkable for two reasons. First, it’s huge (as asteroids go); and second, it’s coming rather close (again, as asteroids go). According to IFL Science (NOTE: The name of the website actually contains a vulgarity that won’t be printed in the Inquisitr), the asteroid in question is between 400-900 meters (1300-2900 feet) across. That’s big; by comparison, the meteorite that exploded over Chelyabinsk, Russia, in 2013, damaging some 1,500 buildings and injuring some 500 people, is was estimated to be one-twentieth that size, according to Russia Today. Not only is Asteroid 2004 BL86 big, it’s coming very close. Scientists measure asteroid approaches in Lunar Distance (LD) — one LD is the distance between the Earth and the Moon, which is about 348,000 kilometers (about 239,000 miles). Scientists consider an asteroid “close” if it comes within about 19.5 LD; Asteroid 2004 BL86 will come in at about three LD. More
