HIP 30104 is located about 83.8 light-years from Sol. It lies in the southwest corner of the constellation Puppis, the Stern of the legendary ship Argo Navis.
HIP 30104 is a yellow-orange main sequence dwarf star of spectral and luminosity type G3-4 V. Similar to Sol[1][2][3][4], this possible "Solar twin" may have roughly the same mass, the same diameter[5][6], and 1.25 times its luminosity. It appears to be almost 1.55 times as enriched than Sol in elements heavier than hydrogen ("metals") based on its abundance of iron[7]. With low chromospheric activity, the star appears to be much older than Sol's 4.6 billion years[8][9].
An Earth-type planet with liquid water on its surface would require a stable orbit centered around 1.1 AU from HIP 30104 -- just over the orbital distance of Earth in the Solar System. Assuming that the star has about one Solar-mass, such a planet would have an orbital period lasting close to 1.2 Earth years or around 430 days.
