Bus-sized asteroid to pass by Earth

Help

Astronomers are watching for an asteroid the size of a double-decker bus which will pass within 70,000km (43,500 miles) of Earth on Friday.

Gareth Williams, of the Minor Planet Centre, told Radio 5 live Morning Reports: "There's absolutely no chance of it hitting us."

He explained: "It's way above the outer reaches of the atmosphere. Even if it were on a trajectory that took it into the atmosphere... objects of that size generally break apart in the upper atmosphere."
