Tau Ceti, Latinized from τ Ceti, is a single star in the constellation Cetus that is spectrally similar to the Sun, although it has only about 78% of the Sun's mass. At a distance of just under 12 light-years from the Solar System, it is a relatively nearby star and the closest solitary G-class star.
Can you see Tau Ceti?
Tau Ceti is slightly smaller and less luminous than our sun. It lies 11.9 light-years away in the constellation Cetus (the Whale) and is visible with the naked eye in the night sky. Because of its proximity and sun-like nature, Tau Ceti has featured prominently in science fiction over the years.
How far away is Tau Ceti F from Earth?
The star Tau Ceti, which lies just 11.9 light-years from Earth, is thought to host five exoplanets, two of which have been posited to lie in the "habitable zone" — that just-right range of distances that could support the existence of liquid water on the planets' surfaces.
