HD 189733 also catalogued as V452 Vulpeculae is a binary star system approximately 63 light-years away in the constellation of Vulpecula (the Fox). The primary star is suspected to be an orange dwarf star while the secondary star is a red dwarf star. Given that this system has the same visual magnitude as HD 209458 it promises much for the study of close transiting extrasolar planets.
