Exoplanets are planets that orbit stars outside of our solar system. They are also known as extrasolar planets. These planets are incredibly diverse and can vary greatly in size, composition, and orbit. Exoplanets were first discovered in the 1990s, and since then, thousands have been identified using various methods, including the transit method, radial velocity method, direct imaging, gravitational microlensing, and more recently, the detection of exoplanet atmospheres.

Exoplanets are of great interest to astronomers because they provide insights into the formation and evolution of planetary systems beyond our own. By studying exoplanets, scientists can learn about the prevalence and diversity of planetary systems in the universe, as well as the conditions that may be conducive to life.

Some exoplanets are located within the habitable zone of their host stars, where conditions might be suitable for the existence of liquid water—a key ingredient for life as we know it. These “potentially habitable” exoplanets are particularly intriguing targets for further study.

The study of exoplanets is a rapidly evolving field in astronomy, with new discoveries being made regularly, expanding our understanding of the cosmos and the possibilities for life beyond Earth.
