A new study involving long-term monitoring of Alpha Centauri by NASA’s Chandra X-ray Observatory indicates that any planets orbiting the two brightest stars are likely not being pummeled by large amounts of X-ray radiation from their host stars. Proxima b is a super Earth exoplanet that orbits a M-type star. This star is a red dwarf that forms a visual double with Alpha Centauri AB. Proxima Centauri is actually part of a triple star system – its two companions, Alpha Centauri A and B, lie out of frame. Proxima Centauri is estimated to have a mass of around 12% of that of the sun. The two brighter components, called A and B, about 0.2 light-year farther from the Sun, revolve around each other with a period of about 80 years, while Proxima circles them with a period of 550,000 years.
