Statistically earth is overdue an asteroid strike but we need to find out more about the orbit of asteroids before we can defend ourselves, warns a space journalist.
A Nasa scientist, Doctor Joseph Nuth, has warned that humans are unprepared for a surprise asteroid or comet that could hit earth.
Broadcaster Sarah Cruddas told Julia Hartley-Brewer that "statistically we’re overdue a strike." However she admits that "sometimes space is so un-relatable that it’s difficult to communicate that message of why we need to be paying attention to it."
Cruddas continued by saying that we'd need to "mathematically work out" how the orbits of asteroids work to defend ourselves. It is a "very new area in terms of science and exploration," but studying this "brings more money back in than you put into it."
