79 Ceti (also known as HD 16141) is a yellow subgiant star approximately 123 light-years away in the constellation Cetus. Its core no longer fuses hydrogen. Eventually the outer layers of the star will expand and cool and the star will become a red giant. Currently 79 Ceti has a luminosity twice that of the Sun.

Planetary system

In 2000, a planet of the star was discovered.[10]
