    As big as 5 football fields: Massive asteroid to be visible from Earth today

    January 26, 2015

    An asteroid the size of five football fields is approaching Earth and is expected to pass by on Monday. It will be visible through strong binoculars – definitely worth a look. The next time such an asteroid comes this close again will be in 2027, a report published in Russia Today said.

    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.


    However, according to astronomers, there is no threat of the object colliding with our planet this time.

     

    “While it poses no threat to Earth for the foreseeable future, it’s a relatively close approach by a relatively large asteroid, so it provides us a unique opportunity to observe and learn more,” Don Yeomans from NASA's Near Earth Object Program at the Jet Propulsion Laboratory said in a statement.
