Ross 128 b

Ross 128 b is a terrestrial planet orbiting Ross 128, completing an orbit every 10 days, about 11 light-years from Earth. It was discovered in 2017 using the radial velocity method.

Ross 128 b lies in the habitable zone of its star, the range of orbits where liquid water could in principle exist on a planet's surface. This makes it a candidate of interest for habitability studies — but lying in the habitable zone is not evidence that the planet is habitable or inhabited; its atmosphere and surface conditions remain unknown.
