This is an asteroid that was visited in order to take a surface sample. Now he is inolved in the mission to explore the asteroid, Apophis. This asteroid will fly past the earth in 2029. It has probably done so on numerous occasions in the past. He is also the author of a book, ‘The Asteroid Hunter’ – and is therefore well up on the subject. He has offered his view – the risk of an asteroid impact is small, but real – and the consequences are large. He made reference to the Chelyabinsk meteor back in 2013. It exploded 14 miles above the surface and was quite a small object as far as space rocks are concerned – yet still managed to do damage down on the surface.
