Iota Draconis (ι Dra / ι Draconis) is an orange giant star located 103 light years away in the constellation Draco. It also has the traditional name Edasich.

Iota Draconis b

Iota Draconis b was discovered in 2001 during a radial velocity study of K-class giant stars and was the first planet discovered orbiting a giant star. It is in an eccentric orbit, which aided its detection as giant stars have pulsations which can mimic the presence of a planet.
