We know more about what's outside our Solar System than what's inside because governments and scientists have prioritized looking out beyond our Solar System.

So what do we know about asteroids?

And as of today, with the use of all the telescopes we have, we have found approximately 14,000 of the estimated five million asteroids the size of or bigger than Chelyabinsk meteor that hit the Earth back in 2013.
In her talk, Danica Remy explains that it's no longer a hypothesis, "How do we defend Earth from an asteroid impact" but rather "Do we choose to defend Earth?", and shares ways how each of us can contribute to detecting dangerous asteroids.
