Astronomers Confirm Exoplanet Barnard b Orbiting Nearby Star

The discovery of Barnard b, a sub-Earth-mass exoplanet, renews interest in the search for habitable worlds near red dwarf stars.

Barnard b is located just six light-years from Earth, orbiting Barnard's star, the closest lone star to our solar system.
Despite its proximity, Barnard b is not habitable due to its high surface temperature of approximately 260 degrees Fahrenheit.
The exoplanet completes an orbit around its host star every 3.15 Earth days, situated extremely close to Barnard's star.
Advanced spectrographic techniques, including the ESPRESSO instrument, were crucial in detecting Barnard b's subtle gravitational effects.
The discovery hints at the potential presence of additional exoplanets in the Barnard's star system, warranting further investigation.
