On any given day, about 90,000 kilograms of dust and small rocks hit the Earth. What happens when something larger is on a collision course with Earth?

Asteroid Hunters by Carrie Nugent was quite an enjoyable read. It’s short, informative, and quite relevant as the recent fly-by of “2014 JO25”, an asteroid with a diameter of 650 meters demonstrated.

If you’ve ever been interested in how scientists really detect potential planet (or hemisphere) killer, or how they might deflect them then this is an excellent book to start with.
