Listen to this lesson:

Asteroids are like the building blocks of our solar system, made from leftovers of planet formation. These rocky bodies can be found mainly in the asteroid belt between Mars and Jupiter. Each asteroid is unique in shape and size, ranging from tiny pebbles to massive rocks stretching hundreds of miles across. Scientists study these celestial objects to learn more about the early solar system and its evolution.

Asteroids play a crucial role in our solar system's ecosystem. They can be thought of as cosmic messengers, carrying valuable information about the conditions of the early solar system. Some asteroids contain metals and water, which are essential for understanding the potential for life on other planets and the future of space exploration. In addition to their scientific importance, asteroids can also pose threats to Earth, making it crucial to monitor and study them closely.

Imagine a future where asteroids could provide resources for building space habitats or fueling long-term space missions. By learning how to harness these resources safely, we could pave the way for humans to live beyond Earth. Exploring asteroids could also reveal secrets about the universe's history and our place within it.
