PLUTO, FARTHEST PLANET & COMET, VISITORS FROM SPACE
(from the Space Files series from York Films of London). Since its discovery in 1930, astronomers have been debating the status of the tiny world at the farthest reaches of our solar system—Pluto. In this program, students are given a firsthand look at the scientific process that initially classified Pluto as a planet and then reclassified it in 2006 as a Dwarf Planet. Also, students will also learn about comets, objects that formed from the earliest galactic activity. Comets orbit the Sun in the Kuiper Belt and the Oort Cloud, and sometimes come a little too close for comfort. http://www.ssrvideo.com/
