The star is located at a distance of approximately 1,140 light years based on parallax measurements, but is drifting closer to the Sun with a radial velocity of −12 km/s.
The star has about the same mass as the Sun and is spinning with a projected rotational velocity of 2 km/s.
It is radiating 25 times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,750 K.[2] In June 2008, the discovery of two extrasolar planets orbiting the star was announced.
[5] The planets were detected using the radial velocity method with the Hobby-Eberly Telescope.
The radial velocity data clearly shows the presence of the inner planet (HD 102272 b).
