HD 23079

HD 23079 is a G-type main-sequence star located approximately 114 light-years away in the constellation Reticulum. This star is notable for possessing an extrasolar planet, designated HD 23079 b.

Stellar Characteristics: HD 23079 is slightly more massive and luminous than our Sun. Its spectral type is G5V, indicating a yellow-dwarf star similar to the Sun in temperature and luminosity class (main sequence). Precise measurements of its properties, such as effective temperature, luminosity, and metallicity, have been carried out using various spectroscopic and photometric techniques.

Planetary System: The known planet orbiting HD 23079, HD 23079 b, is a gas giant with a minimum mass of approximately 2.5 times that of Jupiter. It orbits the star with a period of roughly 492 days and an eccentricity of around 0.17. The planet was discovered using the radial velocity method, which detects variations in the star's velocity caused by the gravitational pull of the orbiting planet.

Significance: HD 23079 is of interest to astronomers studying exoplanets and planetary systems. The relatively close proximity of this star, coupled with the presence of a gas giant planet, makes it a target for further observations aimed at characterizing the planet's atmosphere and searching for additional planets in the system. Understanding the characteristics of systems like HD 23079 helps to broaden our understanding of planet formation and the diversity of planetary systems in the galaxy.
