Some 6,000 cosmic objects circulating around the planet are currently known to experts in the field, the Association of Space Explorers (ASE) told a press conference at the UN headquarters in Vienna, where it presented its report "Asteroid Threats: A Call for Global Response."
And of these, up to 1,000 had a diameter of 150 kilometres (93 miles) or more, meaning they could cause major damage to the Earth's surface, prompting fires, tsunamis and ensuing disasters like famine, it said.
Although it should be possible to predict a collision up to 15 years before it occurs, the technology needed to divert an incoming asteroid has yet to be developed and this will require international cooperation, they said.
We'd better get busy and start cooperating!
