Look out! Nasa warns January 26th asteroid will be Earth's closest call until 2027

Nasa has warned of an impending asteroid pass - and says it will be the closest until 2027.

The asteroid, designated 2004 BL86, will safely pass about three times the distance of Earth to the moon on January 26.

It will be the closest by any known space rock this large until asteroid 1999 AN10 flies past Earth in 2027.

At the time of its closest approach on January 26, the asteroid will be approximately 745,000 miles (1.2 million kilometers) from Earth. 

WHERE IS IT? 

Due to its orbit around the sun, the asteroid is currently only visible by astronomers with large telescopes who are located in the southern hemisphere. 

But by Jan. 26, the space rock's changing position will make it visible to those in the northern hemisphere. 

From its reflected brightness, astronomers estimate that the asteroid is about a third of a mile (0.5 kilometers) in size. 

At the time of its closest approach on January 26, the asteroid will be approximately 745,000 miles (1.2 million kilometers) from Earth.

'Monday, January 26 will be the closest asteroid 2004 BL86 will get to Earth for at least the next 200 years,' said Don Yeomans, who is retiring as manager of NASA's Near Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, California, after 16 years in the position. 

'And 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.'

One way NASA scientists plan to learn more about 2004 BL86 is to observe it with microwaves.

NASA's Deep Space Network antenna at Goldstone, California, and the Arecibo Observatory in Puerto Rico will attempt to acquire science data and radar-generated images of the asteroid during the days surrounding its closest approach to Earth.

'When we get our radar data back the day after the flyby, we will have the first detailed images,' said radar astronomer Lance Benner of JPL, the principal investigator for the Goldstone radar observations of the asteroid. 

'At present, we know almost nothing about the asteroid, so there are bound to be surprises.'

Don't Panic! Nasa says '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.'

Asteroid 2004 BL86 was initially discovered on Jan. 30, 2004 by a telescope of the Lincoln Near-Earth Asteroid Research (LINEAR) survey in White Sands, New Mexico.

The asteroid is expected to be observable to amateur astronomers with small telescopes and strong binoculars.

'I may grab my favorite binoculars and give it a shot myself,' said Yeomans. 

'Asteroids are something special. Not only did asteroids provide Earth with the building blocks of life and much of its water, but in the future, they will become valuable resources for mineral ores and other vital natural resources. 

'They will also become the fueling stops for humanity as we continue to explore our solar system. There is something about asteroids that makes me want to look up.'
