Nearby stellar system mapped in depth
An international research group has characterized the celestial bodies circling Barnard's Star with unprecedented precision. The reddish dwarf lies just under six light-years away and ranks as the nearest star to the Sun after the Alpha Centauri system.
The assembled data portray comparatively small and unusual planets that differ markedly from the arrangement found in our own solar system. Habitable conditions appear to be ruled out on these distant worlds.
- Barnard's Star is the closest star after Alpha Centauri
- Its distance from Earth is less than six light-years
- The accompanying planets are small and considered strange
- Those objects are judged to be uninhabitable
The findings draw on observations that deepen knowledge of planetary systems in the immediate galactic vicinity. Because Barnard's Star is relatively quiet and old, it serves as a key reference for models of world formation around low-mass stars.
Additional investigations are expected to refine the physical properties of the detected objects and to enable comparisons with other nearby stellar systems.
