HD 202206 - Distance, Age and Metallicity

Distance, Age and Metallicity

Measurements by the Hipparcos astrometric satellite give a parallax of 21.58 milliarcseconds, which corresponds to a distance of 46.3 parsecs. It is similar in mass, radius, and luminosity to the Sun, though estimated to be older at around 5.6 Gyr old. It is also more metal-rich than our Sun based on the amount of iron relative to hydrogen.
