Massive Asteroid, As Big As 5 Football Fields, Will Be Visible from Earth On Monday

asteroid_comet_meteor_space_earthAn asteroid the size five football fields is approaching Earth and is expected to pass by on Monday. It will be visible through strong binoculars – definitely worth getting; the next time such an asteroid could be this close again will be in 2027.

At the closest point to the Earth, asteroid 2004 BL86 will be at a distance of 1.2 million kilometers which – approximately three times the distance from the Earth to the moon. Estimated to be 0.5 km in diameter, it is classified by scientists as potentially dangerous.

A space object is considered “potentially dangerous” if it crosses the Earth’s orbit at a distance of less than 0.05 AU (approximately 19.5 distances from the Earth to the Moon), and if its diameter exceeds 100-150 meters. Objects of this size are large enough to cause unprecedented destruction, or generate a tsunami in case they fall into the ocean.

You can watch 2004 BL86’s flyby in visible light (as opposed to radar observations) live online Monday via the Virtual Telescope Project in Italy.
