HD 23079 is a star approximately 114 light years away in the constellation Reticulum. Since the star is magnitude 7.1, it is not visible to the naked eye, but at least in binoculars, it should be easily visible. The spectral type is F8 or G0, it is a main-sequence (hydrogen-fusing) star. The star is larger and more massive than our Sun. As it is typical for planet-harboring stars, it is a population I star, with metallicity of –0.24 dex (58% solar). The age of the star is 6.53 billion years old, older than Sun’s 4.57 billion years.
In October 2001, a giant planet orbiting the star was announced.[1]
