Exploring Space Rocks and Their Journey Through the Solar System

The video explores the fascinating world of space rocks, including asteroids, meteoroids, meteors, and meteorites. It explains the asteroid belt's formation due to Jupiter's gravity and introduces the concept of the snow line. The video also covers the Kuiper belt, the Oort cloud, and the journey of comets. It highlights how comets and asteroids may have brought water and life ingredients to Earth, with the Rosetta mission potentially unlocking secrets about life's origins.
