|} YZ Ceti is a red dwarf star in the constellation Cetus. Although it is relatively close to the Sun at just over 12 light years, this star can not be seen with the naked eye. It is classified as a flare star that undergoes intermittent fluctuations in luminosity. YZ Ceti is only about 8.5% the mass of our Sun, and is normally less than 1/5000 as luminous.

This star is unusually close to Tau Ceti, a star of spectral class G8. The two are only about 0.72 light years apart, less than one-sixth the distance from the Sun to our nearest neighbor, Proxima Centauri.
