L 97-12 (or WD 0752-676, or LHS 34, or Gliese 293) is a nearby degenerate star (white dwarf), located in the constellation Volans, the single known component of the system.

Possibly, L 97-12 is the ninth-closest white dwarf after Sirius B, Procyon B, van Maanen's star, Gliese 440, 40 Eridani B, Stein 2051 B, GJ 1221 and Gliese 223.2. (However, there is probability, that white dwarfs GJ 1087,Gliese 518 and (with lesser probability) Gliese 915 may be located closer.) Trigonometric parallax of L 97-12 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:

The mass of L 97-12 is 0.59 ± 0.01 Solar masses, and its surface gravity is 108.00 ± 0.02 cm·s−2, or approximately 102,000 of Earth's, corresponding to a radius of 8,887 kilometres (5,522 miles), or 139% of Earth's.
