names = HIP 17096 b, SAO 233208 b HD 23079 b is an exoplanet approximately 114 light years away in the constellation Reticulum. The planet has mass of 2.45 Jupiters, classifying as massive jovian; although only the minimum mass is known since inclination is unknown. The planet takes almost exactly two years to orbit the star at the average distance of 1.6 AU. The planets orbital eccentricity is about the same as 109 Piscium b, HD 75898b, and HD 69830b at 0.102. The distance range from as close as 1.44 AU to as far away as 1.76 AU from the parent star. The apparent angular separation between a planet and a star as visible from Earth is 47 milliarcseconds. The speed of stellar wobble caused by a planet [semi-amplitude] is 54.9 m/s.

Since if planet is massive, it would likely be a gas giant comparable to Jupiter, Saturn, Uranus, and Neptune in the solar system. In Sudarsky classification scheme, the planet is probably a water jovian with clouds made mainly from water, as the planet orbits at 1.60 AU from the Sun-like star.

The planet was discovered in 2001 by Tinney et al., who used doppler spectrometer to look for shifts of star’s spectrum caused by a gravity of the planet tug the star around as the planet orbits.
