Teachers TV: Planets, Asteroids and Comets

The wonders of Saturn, asteroids and comets are examined.

Saturn and the Scale of the Solar System: planetary scientist Sheila Kanani shows us the stunning images of Saturn and its moons taken from the Cassini spacecraft. She explains what we know about the planet, how far away it is and how it differs from the Earth. Asteroids and Comets: astronomer Jay Tate reveals the risks and dangers of an asteroid collision on the Earth and explains how our understanding of orbits allows us to track them. We also ask what we might do if we discover an asteroid or comet heading our way. The films are followed by a number of engaging practical demonstrations that teachers can use to follow up these topics in the classroom.
