GJ 3378 b: A 2.3-Earth-mass rocky world in the habitable zone, 25 light-years away, with Earth-like pressure and uncertain atmosphere
To the point
GJ 3378 b is a nearby rocky super-Earth in the habitable zone with about 2.3 Earth masses and Earth-like energy input, but its atmosphere and water are unconfirmed and may have been eroded, and NASA’s Habitable Worlds Observatory planned for the 2040s could determine whether it has an atmosphere or signs of life.
