79 Ceti, also known as HD 16141, is a binary star system located 123[1] light-years from the Sun in the southern constellation of Cetus.
It has an apparent visual magnitude of +6.83,[2] which puts it below the normal limit for visibility with the average naked eye.
However, Houk and Swift (1999) found a class of G8IV,[5] which suggests it has exhausted the supply of hydrogen at its core and begun to evolve off the main sequence.
[4] On March 29, 2000, a planet orbiting primary star was announced, it was discovered using the radial velocity method.
[10] This object has a minimum 0.26 times the mass of Jupiter and is orbiting its host star every 75.5 days.
