HD 73256

HD 73256 is a G-type main-sequence star located approximately 118 light-years away in the constellation Pyxis. This star is similar to our Sun in terms of its spectral classification, being a G9V star, indicating it's slightly cooler and less massive than the Sun.

HD 73256 is known to host at least one extrasolar planet, designated HD 73256 b. This planet is a gas giant, estimated to have a mass several times that of Jupiter. It was discovered through the radial velocity method, which detects variations in a star's motion caused by the gravitational pull of an orbiting planet.

The star is of interest to astronomers studying exoplanets and planetary systems outside our own, as it provides insights into the diversity and formation of planetary systems around Sun-like stars. Further studies of HD 73256 and its planet may help in understanding the conditions necessary for the formation of habitable planets.
