Asteroid and Kuiper Belt Concepts

The video explores the asteroid and Kuiper belts, starting with the discovery of Pluto in 1930, which led astronomers to speculate about other objects beyond Neptune. Gerard Kuiper predicted a belt of icy objects, confirmed in 1992 by David Jewett and Jane Liu. The Kuiper Belt contains icy objects, including Pluto, and some may become comets. The asteroid belt, located between Mars and Jupiter, consists of rocks and ice, with objects ranging from pebbles to dwarf planets. Despite the large number of asteroids, their combined mass is small. Meteorites help us understand asteroid composition, which includes iron, nickel, silicates, and carbon.
