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¦
