HD 73267
This object is a G-type main-sequence star with a stellar classification of G5V. It is roughly eight billion years old with a near-solar metallicity and is spinning with a projected rotational velocity of 1.65 km/s, giving it a rotation period of around 33 days. The star has 90% of the mass and size of the Sun. It is radiating 78% of the Sun's luminosity from its photosphere at an effective temperature of 5387 K.
Planetary system
In October 2008, a candidate planet was discovered orbiting this star. This object was detected using the radial velocity method by search programs conducted using the HARPS spectrograph. Subsequent analysis of collected data suggests the presence of an additional long-period planet in the system with at least 83% of the mass of Jupiter. In 2022, the inclination and true mass of HD 73267 b were measured, and the presence of a second planet was confirmed using a combination of radial velocity and astrometry.
