An international team of researchers has confirmed the existence of Proxima b, an Earth-like planet that is orbiting the closest star to our solar system, Proxima Centauri. They discovered that Proxima b is 1.17 times the mass of earth, smaller than the older estimate of 1.3 times and orbits its star in just 11.2 days. Proxima b was first seen in 2016 using HARPS & researchers were able to hone in on the planet with ESPRESSO.
