Space Agencies Tracking, Asteroid With 'Small Chance' , of Hitting Earth in 2046.br CNN reports that a newly-discovered br asteroid has a slight chance of impacting br Earth on Valentine's Day in 2046.br According to NASA's Planetary Defense Coordination br Office, the asteroid is about 160 feet in diameter, br close to the size of an Olympic swimming pool. .br Data projections by the European Space br Agency suggest that the asteroid has br a 1 in 625 chance of hitting Earth. .br However, CNN reports that NASA's Jet Propulsion br Laboratory's (JPL) Sentry system calculated br that the odds of impact are slightly greater. .br According to the Sentry system, br which tracks potential celestial threats, br the odds of collision are closer to 1 in 560. .br The chance of collision br is extremely unlikely with no cause br for public attention or public concern, Jet Propulsion Laboratory, via CNN.br This object is not br particularly concerning, Davide Farnocchia, navigation engineer at the Jet Propulsion Laboratory in Pasadena, California, via CNN.br However, officials at NASA have warned that those br odds could be altered as more observations of the asteroid br are made and further analysis has been carried out.br Often when new objects are first br discovered, it takes several weeks of data br to reduce the uncertainties and adequately br predict their orbits years into the future, NASA Asteroid Watch, via Twitter.br The asteroid, first spotted on February 2, br is traveling at approximately 15.5 miles per second br and is currently over 11 million miles from Earth.
