Over the course of history, we’ve discovered hundreds of thousands of asteroids. But how do astronomers discover these bits of rock and metal? How many have they found? And how do they tell asteroids apart? Carrie Nugent shares the story of the very first asteroid ever discovered and explains how asteroid hunters search for these celestial bodies.
Lesson by Carrie Nugent, directed by TED-Ed, animation by Reza Riahi.
