Gliese 318
white dwarf in the constellation Pyxis
Gliese 318 is a white dwarf in the constellation Pyxis. Its spectral type is DA5.5 and it has a visual magnitude of 11.85, and lies 27.8 light-years (8.5 parsecs) away.
The star was too faint to have had its parallax measured by the Hipparcos satellite. Earth-based measurement in 2009 gave its parallax as 113.63±1.97 milliarcseconds, yielding a distance of 28.7±0.5 light-years; this parallax measurement has since been substantially improved by Gaia.
Gliese 318 is a rather young white dwarf with an age estimated to be 590 million years. Its temperature is around 9,000 K and it shines with 0.13 percent of the luminosity of the Sun. Like all white dwarfs, Gliese 318 is small, with just 1.5 percent the Sun's radius (1.6 R🜨), but has around half the Sun's mass.
Bragaglia et al. suspect this star to be a double white dwarf due to strong spectral line variations. From Gaia DR2 it was not possible to confirm this claim.
“Gliese 318” enters the record as white dwarf in the constellation Pyxis. Crown Archives preserves that source wording while asking what Gliese, white and dwarf can confirm, complicate or overturn.
Why this record matters
“Gliese 318” is worth following because a concise public description often conceals a longer documentary argument. Here, Gliese, white and dwarf provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Feb 4, 2026. The linked authority identifier is Q5880882. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2009.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
