Small near-Earth asteroid 2012 DA14 will pass very close to Earth on February
15, so close that it will pass inside the ring of geosynchronous weather and
communications satellites. NASA's Near-Earth Object Program Office can
accurately predict the asteroid's path with the observations obtained, and it is
therefore known that there is no chance that the asteroid might be on a
collision course with Earth. Nevertheless, the flyby will provide a unique
opportunity for researchers to study a near-Earth object up close. Here are the
facts about the safe flyby of Earth of asteroid 2012 DA14 -- a record close
approach for a known object of this size.
Asteroid 2012 DA14 will be closest to Earth on Feb. 15 at approximately 19:24
UTC (2:24 p.m. EST/11:24 a.m. PST). This time may change by a minute or two as
the asteroid is tracked on its approach and predictions are refined.
At
the time of closest approach, the asteroid will be over the eastern Indian
Ocean, off Sumatra -- approx. latitude: -6 deg South. / longitude: 97.5 deg
East.
The orbit of asteroid 2012 DA14 is well understood – it will not come any closer
than 17,150 miles (27,650 kilometers) above Earth's surface during its flyby on
Feb 15, 2013.
The asteroid’s orbit around the sun is roughly similar to
that of Earth, and it makes relatively close approaches to our planet’s orbit
twice per orbit. But, the 2013 flyby is by far the closest the asteroid will
approach our planet for many decades. The next notable close approach to Earth
will be on February 16, 2046, when the asteroid will pass no closer than 620,000
miles (1,000,000,000 kilometers) from the center-point of Earth.
