Gliese 318 is a

white dwarf A white dwarf is a stellar core remnant composed mostly of electron-degenerate matter. A white dwarf is very dense: its mass is comparable to the Sun's, while its volume is comparable to the Earth's. A white dwarf's faint luminosity comes ...

is DA5.5 and it has a visual magnitude of 11.85, which lies 26 light years away. The star was too faint to have had its parallax measured by the '' Hipparcos'' satellite. Earth-based measurement gives its parallax as 113.63 ± 1.97 milliarcseconds, yielding a distance of 28.7 ± 0.5 light-years. It is around 45% as massive as the Sun but has only 0.15% its luminosity.
