Gliese 877 (GJ 877 / HIP 113229 / LHS 531)[1] is a red dwarf located in the southern constellation of Octans, near the boundary with Indus.
Gliese 877's bolometric luminosity is just 2.3% of our sun's.[3] It shines with an apparent magnitude of +10.22, so it cannot be seen with the naked eye. Nevertheless, it is considerably brighter than other red dwarfs, such as Proxima Centauri, the closest red dwarf to our Solar System; in particular, it is almost 14 times more luminous than Proxima. Of spectral type M3V,[4] its effective temperature is 3390 K.[3] It does not appear to be a variable star.[4]
Gliese 877 is 28.1 light years from the Solar System.[1] Known stars close to it are β Hydri and ζ Tucanae, respectively 4.5 and 6.2 light years.[5]
