A Second Planet Orbiting Proxima Centauri The Closest Star To The Sun May Have Been Discovered
According to a study published in the journal Science Advances, the planet may be a “super-Earth”—exoplanets with masses higher than Earth’s but significantly lower than those of Uranus and Neptune. One planet, known as Proxima b, has already been detected around the star, which is a red dwarf—meaning it has a relatively low temperature, diameter and mass (about an eighth that of the Sun’s.) “For such type of star we expect systems of low-mass planets to be common around them,” Mario Damasso, from the INAF Astrophysical Observatory of Turin, told Newsweek....
