Audience: 3rd grade and older

In the first view, this slide illustrates the difference in speed between a car and an airplane. In the second view, the speed of an airplane is compared to that of two interstellar objects, Oumuamua and Bennu. A third view shows the size difference between these two bodies and an average airplane.

Key messages: Asteroids move much faster than airplanes; and are also much bigger.
