 | | Given also that the object was quite large as earth-approaching asteroids go, perhaps one mile across, it was added to the list of "potentially hazardous objects" (PHAs) that need to be monitored, lest they are destined to come dangerously close to the earth over the course of the next several centuries. |
 | | Nevertheless, it should be quite accessible for a while with large telescopes, which in addition to helping establish whether a collision in 2028 is possible, could usefully provide more definite information about the object's size. |
 | | The asteroid "is predicted to pass at a rather comforable distance of about 600,000 miles (about 960,000 kilometers) in 2028," reported Dr. Donald K. Yeomans and Dr. Paul W. Chodas, JPL scientists who specialize in computing the predicted orbits of comets, asteroids, planets and other bodies in the solar system. |
