HD 23079 b
HD 23079 b is an exoplanet approximately 114 light years away in the constellation Reticulum. The planet has mass of at least 2.45 Jupiters, 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 planet's orbital eccentricity is about the same as 109 Piscium b, HD 75898 b, and HD 69830 b 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 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.
