Gliese 581 is a red dwarf star approximately 20 light-years from Earth in the constellation Libra. It has been the subject of significant exoplanet research and was notable as the host star of Gliese 581c, one of the first potentially habitable terrestrial exoplanets discovered.
Planetary system
The Gliese 581 system contains several confirmed exoplanets, with Gliese 581c being the most notable as it was initially considered potentially habitable when discovered in 2007. The system has been extensively studied by exoplanet researchers due to its proximity to Earth and the potential for habitability of its planets.
