Unlocking the Secrets of Space Rocks

Understanding the age of asteroids like Selam, the "moonlet" orbiting the asteroid Dinkinesh, is crucial not just for the thrill of space exploration but for piecing together the history and evolution of our solar system. These celestial bodies are the building blocks left over from the solar system's formation, and studying them helps scientists understand the processes that shaped Earth and other planets. By learning how asteroids are formed and evolve, you can grasp the dynamics of larger astronomical phenomena and possibly predict future cosmic events. This knowledge could even play a role in protecting Earth from potential asteroid impacts. Plus, isn't it fascinating to think about how these space rocks have been whirling through space for millions of years?
