An Earth-like Stellar Wind for Proxima Centauri c

An Earth-like stellar wind for Proxima Centauri c

Proxima Centauri, the closest star to the Sun, is the faint red dot inside the red circle. A second planet, Proxima c, was recently discovered orbiting Proxima Cen every 5.3 years. Astronomers calculating the likely effects of the star’s wind on the planet conclude that a possible atmosphere would experience Earth-like conditions. Credit: Skatebiker

Proxima Centauri is the closest star to the Sun, and its planet, Proxima Cen b (“Proxima b”), lies in its habitable zone (the distance range within which surface water can be liquid), making the planet a prime target for exoplanet characterization. The star is an M-dwarf with a mass of only 0...
