The WISE guy has hit some pay celestial pay dirt.
NASA’s Wide-field Infrared Survey Explorer, launched in December – took this shot of a near earth asteroid on January 12th. Designated 2010 AB78 – (comets have much more fun names…) this asteroid is 158 million kilometers (98 million miles) from Earth. Diameter is one kilometer or 6 tenths of a mile. Scientists say this space rock is not on a path to collide with earth in the foreseeable future.
But an expert panel has just concluded we are not being so wise about conducting a survey of big near earth asteroids that could clonk us and wreak havoc. The National Research Council says the goal to find 90% of the earth threatening asteroids 460 feet/ 140 meters or larger 2020 will not be met – for lack of funding. Scientists say an asteroid as small as a hundred feet – or 30 meters across – could take out a city. If you don’t think this is money well spent – go ask a dinosaur what he or she thinks.
