Understanding Asteroids and Comets

Definition and Characteristics of Asteroids

Asteroids are rocky objects that orbit the Sun and are primarily found between Mars and Jupiter, in a region known as the asteroid belt. They vary in size, with some reaching hundreds of kilometers in diameter, while others are as small as a few meters. Asteroids come in various shapes, including irregular and spherical, and their composition is diverse, with a combination of rock, metal, and sometimes even organic compounds.

Definition and Characteristics of Comets

Comets, on the other hand, are icy objects often referred to as "dirty snowballs." They originate from regions in the outer solar system, such as the Kuiper Belt and the Oort Cloud. Comets are composed of ice, dust, and various organic compounds. As they approach the Sun, the heat causes the ice to vaporize, creating a glowing coma and a tail that points away from the Sun.
