Star system, 31 light-years
Wolf 1069 and its one planet
Wolf 1069 b is an exoplanet about 1.08 times Earth's width (a size estimated from its mass), 31 light-years away, orbiting in its star's computed habitable zone.
Wolf 1069 is a star of spectral type M5.0 V, 31 light-years from us, with one known planet.

Wolf 1069 b
Wolf 1069 b is an exoplanet about 1.08 times Earth's width (a size estimated from its mass), 31 light-years away, orbiting in its star's computed habitable zone.

It was found by the back-and-forth wobble its pull puts into its star's motion, seen as a shift in the colour of the star's light in 2023. Its orbit lies inside the conservative habitable zone computed for its star (liquid water on a rocky world's surface would be possible there, which says nothing about whether any is).
