Gliese 293 (or WD 0752-676, or LHS 34, or L 97-12) is a nearby white dwarf star, located 26.64 light-years away in the constellation Volans. It is the nearest star in this constellation and also the only one within 10 parsecs.

Distance

Gliese 293 is the 12th-nearest known white dwarf. A trigonometric parallax of Gliese 293 was included in the YPC (Yale Parallax Catalog), and subsequently it was measured more precisely in CTIOPI (Cerro Tololo Inter-American Observatory (CTIO) Parallax Investigation) 0.9 m telescope program, and by Gaia.

Physical parameters

The mass of Gliese 293 is , and its surface gravity is , or approximately 102,000 times Earth's, corresponding to a radius of 8887 km, or 139% of Earth's.

Gliese 293 has a temperature of , almost like the Sun, and a cooling age, i.e. age as a degenerate star (not including its lifetime as a main-sequence star and a giant star) of It has a white appearance due to similar temperature to Sun.
