Podcaster: Dr. Al Grauer
Title: Travelers in the Night 679 & 680: Hammer & Comets and Asteroids
Organization: Travelers in The Night

Description: Today’s two stroy:
- When Asteroid Hunters find a relatively large asteroid on a collision course with planet Earth, the challenge is to change its path to make it miss our home planet.
- If you set your mind to it, you can find and hold a sample of an asteroid, called a meteorite, which has landed on the Earth’s surface. On the other hand, watching major meteor showers will allow you to see but not touch comet dust as it enters and burns up in the Earth’s atmosphere.
