An Asteroid Flyby is expected on February 15. Small near-Earth asteroid 2012 DA14 will pass very close to Earth, 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.
What date and what time will the asteroid be closest to Earth?
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.
Could asteroid DA14 hit and impact Earth?
No. 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.
How big is asteroid 2012 DA14?
Asteroid 2012 DA14 is currently estimated to be about 150 feet (45 meters) across and has an estimated mass of about 130,000 metric tons. If radar observations of this asteroid are successful, we might have a more accurate estimate of the asteroid’s size after its close approach.
How fast will the asteroid be traveling at closest approach?
Asteroid 2012 DA 14 is traveling at about 17,450 miles per hour (28,100 kilometers per hour), or 4.8 miles per second (7.82 kilometers per second) relative to Earth.
