- Astronomers discovered GJ 251 c, a rocky exoplanet almost 4 times the mass of Earth, orbiting a nearby dwarf star less than 20 light-years away.
- The planet lies in the habitable “Goldilocks Zone”, where liquid water could exist if it has the right atmosphere.
- Discovery made using the Habitable-Zone Planet Finder (HPF), analyzing over 20 years of data.
- Researchers detected the planet by observing the “wobble” of its host star, caused by the planet’s gravity.
