An exoplanet is a planet that orbits a star outside our solar system. These planets vary widely in size, composition, and distance from their parent stars, and can be similar to the planets in our solar system or very different.
Some of them are located in the "habitable zone" of their stars, where conditions might be right for liquid water to exist on their surfaces. This zone is often referred to as the "Goldilocks zone" because it's not too hot and not too cold, making it a prime area in the search for potential life beyond Earth.
Few notable exoplanets:
Proxima Centauri b: Located in the habitable zone of Proxima Centauri, the closest known exoplanet to Earth.
TRAPPIST-1 planets: Seven Earth-sized planets orbiting the ultra-cool dwarf star TRAPPIST-1, some of which are in the habitable zone.
Kepler-452b: Dubbed "Earth's cousin," it orbits a star similar to our Sun and is located in the habitable zone.
HD 209458 b(nicknamed Osiris): One of the first exoplanets discovered to transit its star.
WASP-121b: A "hot Jupiter" exoplanet with extreme atmospheric conditions, such as high temperatures and potential exotic states of matter.
