We missed the Chelyabinsk meteorite. Shall we skip the others?

Stephen Hawking once called asteroids the main threat to life on Earth. But our technologies allow us to look at distant galaxies and nebulae. How can you not notice a huge “space boulder” approaching the planet? Nevertheless, on February 15, 2013, this is exactly what happened: the asteroid that exploded over Chelyabinsk was not tracked by any observatory in the world.

But how did it happen? Are we not able to detect an asteroid approaching the Earth? And do we have a plan of action if we do find it? For answers to these questions, Derek Miller turned to Professor David Jewitt, one of the discoverers of the Kuiper Belt.
