dryriver writes "CNN reports: 'On a day when global doomsday predictions failed to pan out, NASA had more good news for the Earth: An asteroid feared to be on a collision course with our planet no longer poses a threat. Uncertainties about the orbit of the asteroid, known as 2011 AG5, previously allowed for a less than a 1% chance it would hit the Earth in February 2040, NASA said. To narrow down the asteroid's future course, NASA put out a call for more observation. Astronomers from the University of Hawaii at Manoa took up the task and managed to observe the asteroid over several days in October. "An analysis of the new data conducted by NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, California, shows that the risk of collision in 2040 has been eliminated," NASA declared Friday. The asteroid, which is 140 meters (460 feet) in diameter, will get no closer to Earth than 890,000 kilometers (553,000 miles), or more than twice the distance to the moon, NASA said. A collision with Earth would have released about 100 megatons of energy, several thousand times more powerful than the atomic bombs that ended World War II, according to the Gemini Observatory.'"
