HD 189733 is a star located about 64.5 light-years away in the constellation Vulpecula. It is classified as a K-type main-sequence star, which means it is cooler and less luminous than our Sun. The star is known for hosting a giant exoplanet, HD 189733b, which is one of the first exoplanets to be studied in detail. HD 189733b is a hot Jupiter, characterized by its large size and close orbit around its star. It has extreme weather conditions, including high-speed winds and possible glass rain. The study of this system has provided valuable insights into the atmospheres of exoplanets and their potential habitability.
