Distance from Earth: 3.3 parsecs (10.7 light years)
The radial velocity (Doppler) method detects the slight wobble a planet induces in its host star as both bodies orbit their common center of mass. By measuring tiny shifts in the star's spectral lines, astronomers can infer the planet's minimum mass and orbital period. This was the first technique to successfully detect exoplanets around Sun-like stars.

544 K is outside the range for liquid water (180-310 K).
Receives 20.90x Earth's insolation, outside the habitable zone.
This planet orbits outside the estimated habitable zone of its star.
Habitability assessments are rough estimates based on limited available data. True habitability depends on many additional factors including atmospheric composition, magnetic field presence, tidal locking, and stellar activity. These assessments should not be considered definitive.
