Radius of proxima b
As of 2024, three planets (two confirmed and one candidate) have been detected in orbit around Proxima Centauri, with one being among the lightest ever detected by radial velocity ("d"), one close to Earth's size within the habitable zone ("b"), and a possible gas dwarf that orbits much farther out than the inner two ("c"). WebProxima b is the closest known planet outside our solar system. The star Proxima Centauri was discovered in 1915 by the Scottish born astronomer Robert Innes.

The minimum value is obtained considering a 1.10 M ⊕ Mercury-like planet with a 65% core mass fraction, whereas the highest radius is reached for 1.46 M ⊕ with 50% water in mass, constituting an ocean planet.
WebOct 7, 2016 · If Proxima b’s radius measured closer to the higher end of the calculation, things could get much deeper. In this case, the most accurately simulated scenario posits that the exoplanet is composed of a rocky core surrounded by as much as 120 miles of ocean.
