Host Star
HD 154672 is a sunlike G-type star that has a mass of 1.06 times that of the Sun and a radius that is 1.27 times that of the Sun. Thus, it is slightly larger than the Sun, although it has a similar mass. The star has an effective temperature of 5714 K, slightly cooler than the Sun; however, it is far richer in iron, with a measured metallicity of = 0.26. This means that the star has 1.82 times more iron than the Sun does. HD 154672 is far older than the Sun, as its estimated gyrochronological age is estimated at 9.28 billion years. HD 154672's spectrum suggests that the star's chromosphere (its outer layer) is not active.
HD 154672 is located 65.8 parsecs (214.6 light years) away from Earth. It has an apparent magnitude (V) of 8.22, making the star too dim to see from Earth with the naked eye. The star is slightly dimmer than planet Neptune as perceived with the naked eye, which has an apparent magnitude of 7.78 at its brightest. The star's actual brightness is measured with an absolute magnitude of 4.12, similar to that of the Sun.
