Comets and Asteroids

Have you ever wondered what zooms through space besides planets and moons? This worksheet helps you explore comets and asteroids, two fascinating types of space objects that travel around the Sun. You learn what they are made of, where they come from, and how they behave as they move through the solar system. Each activity breaks the information into simple, friendly steps. As you learn, outer space becomes easier to understand and more exciting to imagine.

You begin by discovering asteroids, rocky objects that orbit mostly in the asteroid belt between Mars and Jupiter. These space rocks come in many shapes and sizes, from tiny pebbles to objects hundreds of miles wide. Activities help you see how asteroids formed from leftover building materials of the early solar system. You start recognizing them as important clues about how planets were made.

Next, you explore comets, icy bodies that come from far-off places like the Kuiper Belt and Oort Cloud. When comets get close to the Sun, heat causes their ice to turn into gas, forming a glowing coma and a long, beautiful tail. You learn why the tail always points away from the Sun and what makes comets shine so brightly. These activities help you compare comets and asteroids in fun and simple ways.
