HD 104067 is a star with a planetary system in the southern constellation of Corvus. It has an apparent visual magnitude of 7.92[2] which is too faint to be visible with the naked eye. The distance to this star is 66.4 light-years (20.4 parsecs) based on parallax. It is drifting further away with a radial velocity of +15 km/s.[1]
This is an ordinary K-type main-sequence star with a stellar classification of K3V.[3] It is a moderately active star[8] with an age of roughly five billion years. HD 104067 is spinning with a projected rotational velocity of 2.5 km/s,[4] giving it a rotation period of approximately a month.[3] The star has 82% of the mass and 77% of the radius of the Sun.[4] It is radiating 31%[5] of the Sun's luminosity from its photosphere at an effective temperature of 4,942 K. The metal content of this star is close to that in the Sun.[4]
