Nasa’s asteroid collision: How many asteroids are really out there?

BBC World Service - More or Less, Nasa’s asteroid collision: How many asteroids are really out there?

As Nasa rams an asteroid to try and alter its course, how many are yet to be discovered?

As a Nasa craft slams into an asteroid to try and divert its course, we ask how many there really are – and how dangerous they might be to Earth.

This week Nasa slammed a spacecraft into an asteroid in the hope of diverting its course. The Double Asteroid Redirection Test or DART mission will help scientists understand how easy it would be protect Earth if one was headed in our direction. More Or Less first discussed this in 2016 with a little help from the movie Armageddon – with listeners getting in touch once again we ask how many asteroids are really out there and how dangerous they might be to Earth.
