Comets and Asteroids Characteristics

The video explores the differences between asteroids and comets, focusing on their composition, size, and visibility. Asteroids are larger, rocky, and metal-based, while comets are icy with long tails. Comet Halley, a famous comet, is discussed for its periodic visibility from Earth. The video concludes by marveling at the universe's wonders.
