Iota Horologii (ι Hor, ι Horologii) is a solar twin, yellow dwarf star approximately 56 light-years away in the constellation of Horologium (the Pendulum Clock). The star is classified as a G0Vp yellow dwarf (it has previously been classified as G3 and a subgiant ). It has a mass and radius larger than the Sun, and is about 50% more luminous.
As of 1998, a single extrasolar planet is known orbiting Iota Horologii. Because the planet orbits in a near Earth orbit, Iota Horologii was ranked 69th in the list of candidates for NASA's planned Terrestrial Planet Finder mission. In 2000, a dust disc was announced around the star, but this was later determined to be an instrumental artifact.
