Iota Horologii is a bright yellow dwarf star, also known as HR 810. Contains the first planet discovered with an ESA instrument. This is an Eccentric Jupiter (over twice Jupiter's mass) and orbits almost as far as the Earth does from the Sun. Because of the greater luminosity of its star (50% more than the Sun), this planet is also considered a Hot Jovian. Stability analysis indicates that Earth-sized trojan planets could exist around this planet's orbit. A dust disk was announced around this star in 2000, but was later retracted as being due to an instrument defect. Another planet was also proposed, but retracted. System has a low C/O ratio like the Solar System.
