EXOs is an informal shorthand sometimes used to refer to exoplanets—the planets that orbit stars other than the Sun. It is not a formal term in most scientific literature; standard usage remains exoplanets or exoplanetary systems. The label may appear in science communication and educational contexts as a concise way to reference discoveries beyond our Solar System.
Exoplanets are detected by several methods. The transit method observes periodic dips in a star’s brightness
Exoplanets exhibit a wide diversity in size, composition, and orbits. They range from Earth-sized rocky worlds
The study of exoplanets informs theories of planetary formation and evolution and underpins the ongoing search
