Alpha Centauri, Triple Star System


Chandra observations indicate the two brightest stars in Alpha Centauri are not pummeling any orbiting planets with large amounts of X-rays. Alpha Centauri is a triple star system that is only about 25 trillion miles from Earth, and contains the closest star to our Sun. Two of the three stars in Alpha Centauri closely resemble the Sun, making it a prime target in the search for life-hosting exoplanets. Chandra has monitored the Alpha Centauri system every six months for over a decade, providing valuable information about its stars.
