UZ Fornacis (abbreviated as UZ For) is a binary star in the constellation of Fornax. It appears exceedingly faint with a maximum apparent magnitude 17.0. Its distance, as measured by Gaia using the parallax method, is about 780 light-years (240 parsecs).
The system consists of two stars, a white dwarf and a red dwarf, in close orbit around each other. It is hypothesized that there are also two planets orbiting the central stars.
