There's a 1-in-300 chance that a recently discovered asteroid, believed to be about 1,300 feet long, could hit Earth in 2029, a NASA scientist said Thursday, but he added that the perceived risk probably will be eliminated once astronomers get more detail about its orbit.

Keeping an eye on Apophis UK boffins have come up with a plan to track the potentially planet-busting asteroid Apophis, according to a report on the BBC News website. The 300m-wide chunk of space debris is expected to make a close fly-by of Earth in 2029. Initial reports suggested it might actually collide with us, but more refined calculations allayed those fears.â¦

This summer, NASA will launch a robotic probe to visit two stange and giant asteroids -- one is covered with ice while the other may have been blasted by an ancient supernova. The tales these asteroids tell may reveal the true beginnings of our solar system.

PARIS  -- A rock measuring less than 10 metres (33 feet) across zipped past the Earth at the closest distance ever detected, but it would not have posed any threat if it had struck our planet, astronomers said.      The "very small" asteroid missed the Earth on March 31 by the wafer-thin gap of 6,500 kilometers (4,000 miles), according to an email circulated by the international network NEO News (NEO stands for Near-Earth Object)...
