What is the main goal of studying exoplanets?

The main goal of studying exoplanets is to learn about the variety and nature of planets beyond our solar system. Scientists want to find out how common planets like Earth are, how they form, and if any could support life. By discovering and studying exoplanets, astronomers hope to answer big questions: Is Earth unique? Are there other worlds like ours? Could life exist elsewhere in the universe? The search for exoplanets helps us explore possibilities for life and understand more about our place in space.
