The recently discovered object, known as comet ISON, is due to fly within 1.2 mln miles (1.9 mln km) from the center of the sun on November 28, 2013 said astronomer Donald Yeomans, head of NASA's Near Earth Object Program
at the Jet Propulsion Laboratory in Pasadena, Calif.
"Nibiru is ridiculous because it doesn't exist - it never existed as anything other than a figment of the imagination by pseudo-scientists who don't seem bothered by a complete lack of evidence," astronomer Don Yeomans, manager of NASA's Near-Earth Object program
office at the Jet Propulsion Laboratory in Pasadena, Calif., told SPACE.com.
Scientists at NASA's Near-Earth Object Program
, which tracks asteroids and comets, ruled out any chance of impact.
Yeomans, a manager at NASAAAEs Near-Earth Object Program
Office, said that even if just dust particles are found, AoweAAEll be looking at leftover debris from the early solar-system formation process.
The near- earth object program
office of NASA's Jet Propulsion Laboratory also computed an orbit solution for this object, and determined that it was not headed for an impact.
Upon further evaluation, those reports were forwarded to the Minor Planet Center at Harvard University, and eventually on to the Near-Earth Object Program
operated by the Jet Propulsion Laboratory at NASA.

Office "has not changed its current estimates for the very low probability (1 in 45,000) of an Earth impact by the asteroid Apophis in 2036," Brown said.
Their method uses object program
dependence graph (OPDG) and other static information to reduce the information to be traced during execution.
"Anything smaller might be a problem, but a local problem," says Donald Yeomans, director of NASA's Near-Earth Object Program
Office in Pasadena, California.
A researcher with the European Space Agency's Near-Earth Object program
(https://www.yahoo.com/news/close-call-passing-asteroid-test-earths-warning-systems-142933732.html) told AFP that the scientists involved in the test pretended that the asteroid was actually a critical object, one that was threatening to Earth, and reacted accordingly.

manager Donald Yeomans said that there will is 1 in 63,000 chance that the 1,300-foot asteroid, called 2013 TV135, will collide with Earth when it comes back on Aug.
those will be valid candidates that could be certified targets," said Paul Chodas, senior scientist at the NASA Near-Earth Object Program
From these calculations, NASA's Near-Earth Object Program
is focusing its efforts on finding 90% of the estimated 100,000 near-Earth objects larger than 140 meters across, using a number of ground-based telescopes either in operation now (such as those used by the Catalina Sky Survey, Spacewatch, and LINEAR) or in the development or planning stages (Pan-STARRS and LSST).
Donald Yeomans, manager of NASA's Near-Earth Object Program
, said the reports appear to be consistent with a meteor shower.
