Star in the constellation Pisces

Gliese 908 is a red dwarf star, located in constellation Pisces at 19.3 light-years from Earth. It is a BY Draconis variable star with a variable star designation of BR Piscium. Its apparent magnitude varies between magnitude 8.93 and magnitude 9.03 as a result of starspots and varying chromospheric activity.

The variability of Gliese 908 was confirmed in 1994, although no period could be detected in its brightness changes.[16] It was entered into the General Catalogue of Variable Stars in 1997.[17]

Gliese 908 is a cool main sequence star, a red dwarf, with a spectral class of M1V Fe-1. The suffix indicates a noticeable deficiency in heavy elements.[4]
