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.

Famous quotes containing the word age:
“Nothing dates one so dreadfully as to think someplace is uptown.... At our age one must be watchful of these conversational gray hairs.”
