Proxima Centauri, an M-class red dwarf and the closest star to us, has been in the scientific news. A recent publication by Guillem Anglada-Escudé et al. [1] presents evidence for the presence of a potentially habitable exoplanet orbiting Proxima Centauri. A periodic Doppler shift has been found in the spectrum of the star, which is likely due to the gravitational pull of a planet. Lying within the temperature zone of Proxima Centauri, with a minimum mass of roughly 1.3 Earth masses, this newly discovered world may be habitable.
