Asteroids: Data Files:
|Summary:||This asteroid will headed towards a very close passage by Earth on February 15, 2013.|
|Description:||Discovered by the LaSagra observatory in southern Spain, the small asteroid 2012 DA14 will pass within about 3.5 Earth radii of the Earth's surface on February 15, 2013. Asteroid 2012 DA14 will pass inside the geosynchronous satellite ring, located about 35,800 km above the equator. Its orbit about the sun can bring it no closer to the Earth's surface than 3.2 Earth radii on February 15, 2013. On this date, the asteroid will travel rapidly from the southern evening sky into the northern morning sky with its closest Earth approach occurring about 19:26 UTC when it will achieve a magnitude of less than seven, which is somewhat fainter than naked eye visibility.|
V1.2: Final Elliptical Orbit with data from JPL/SSD as of Feb 17, 2013.
The orbit in Celestia now fits to the official nominal distance by NASA at close approach of 0.000228014367874602 AU (34,110.5 km) on Feb 15, 2013 - 19:26 UTC. In Celestia the distance is approx. 39,200 km (+5,089.5 km). It seems like that formerly published data were uncertain (even 1 day before the event).
V1.1: Corrected Elliptical Orbit
Nevertheless the distance to Earth shown in Celestia is still not correct (1,378,000 km instead of 34,110.5 km on Feb 15, 19:26 UTC); Adirondack doesn't know whether this is because the VSOP orbit for Earth or inaccurate data of JPL/SSD of 2012 DA14.
