How Spacecraft ACTUALLY Dodge Asteroids

From StarTalk.

How empty is our solar system? Neil deGrasse Tyson and Chuck Nice break down how to navigate an asteroid field in a spacecraft. Should we be hearing about more asteroid crashes?

Learn about the discovery of the asteroid belt between Mars and Jupiter. What were the first asteroids to be discovered? We explore how many asteroids are in our solar system, what the Oordt Cloud is like, Neil’s Asteroid, and another thing that Star Wars got wrong. Why did Voyager never crash into anything?
