Several circumstances invest the star Alpha Centauri, one of the brightest in our southern sky, with special interest. It was one of the earliest whose annual parallax (from which is deduced its distance) was approximately ascertained. It is, so far as at present known, by much the nearest of the fixed stars to our system. It is perhaps the most magnificent of double stars. And (what invests it with special interest to us) it is, from its great southern declination, invisible to the Observatories of the Northern Hemisphere. Science is therefore dependent entirely upon southern observations for all that can be known of the relative movements of its components. Its distance from the solar system is about 225,000 times that of the earth from the sun. Includes illustration
