The first asteroid sample collected in space by NASA has been successfully returned to Earth.

Planet Earth is about to receive the biggest sample yet from an asteroid.

Asteroid 1994PC1 gets close enough that people with backyard telescopes can see it.

In a recent episode of the podcast “Space Curious,” planetary scientists helped us understand why this is. They also explained how we know where asteroids are, and why we’re not all going to get squashed by one anytime soon. “The main reason we go to Bennu is because it is the most potentially hazardous asteroid,” Campins said. “It’s a primitive asteroid,” Campins said. Campins said when someone reads about an asteroid headed for Earth, it’s a good idea to do some fact checking.
