KOI-256
KOI-256 is a double star located in the constellation Cygnus approximately from Earth. While observations by the ''Kepler'' spacecraft suggested the system contained a gas giant exoplanet orbiting a red dwarf, later studies determined that KOI-256 was a binary system composed of the red dwarf orbiting a white dwarf. ==Name==
The acronym "KOI" comes from ''Kepler object of interest'' and means that the object has been cataloged by the ''Kepler'' spacecraft during its search for extrasolar planets using the transit method. The "256" is the number of the object.
