  Tau Ceti - Wikipedia, the free encyclopedia
Tau Ceti (τ Cet / τ Ceti) is a star commonly mentioned by science fiction authors since it is similar to the Sun in mass and spectral type in addition to being relatively close to us.
However, Tau Ceti is a "metal-deficient" star and therefore is thought to be less likely to have rocky planets around it.
Tau Ceti can be seen with the unaided eye as a faint star in the constellation of Cetus.

 Tau Ceti
Tau Ceti has been the target of many SETI (Search for Extraterrestrial Intelligence) programs including the first, Project Ozma, which also looked at Epsilon Eridani.
It is also the first star to be found to have a disk of dust and comets around it similar in size and shape to the disk of comets and asteroids that orbits the Sun.
However, the similarity ends there because it appears that Tau Ceti has more than ten times the number of comets and asteroids that there are in our Solar System.

 Tau Ceti
There also may be an optical companion star seen in telescopes that is not actually bound by gravity to Tau Ceti, and the star does not appear to have a dim stellar or substellar companion based on astrometric measurements (Lippincott and Worth, 1980) or radial velocity variations (Campbell et al, 1988).
Given Tau Ceti's estimated age of 10 billion years, the estimated mass of its dust disk fits its expected decline with time compared to the disk mass of the younger nearby star Epsilon Eridani, which may only be 500 million to one billion years old.
Modelling of Tau Ceti's dust disk observations by the astronomers indicate, however, that the mass of the colliding bodies up to 10 kilometers (6.2 miles) in size may total around 1.2 Earth-masses, compared with 0.1 Earth-masses estimated to be in the Solar System's Edgeworth-Kuiper Belt (Greaves et al, 2004).

 Spotlight: A world apart
Those hoping to find ET in the relatively near star system of Tau Ceti, in the constellation of The Whale will be sorely disappointed to learn that there is some ten times as much material orbiting the star in the form of asteroids and comets as there is orbiting the Sun.
Tau Ceti is a "mere" twelve light years away and is the nearest Sun-like star to Earth, it can be seen clearly in the night sky without the aid of binoculars or a telescope.
Even though Tau Ceti is the nearest Sun-like star, any planets that might orbit it would not be likely to support life as we know it because of the frequent and devastating impacts they would sustain from the asteroids and comets.

 Spectral Type G - Tau Ceti
Tau Ceti is such a G-type, sunlike star, devoid of stellar companions and close enough for detailed studies.
Though Tau Ceti has about half the sun's luminosity, its habitable zone still comprises about one third AU - this is wide enough that a terran planet may have formed there.
Tau Ceti may contain ten times as much material in the form of asteroids and comets than our own solar system, which would crash into any planets at uncomfortable high rates.

 Ceti Alpha - Wikipedia, the free encyclopedia
In the fictional Star Trek universe, Ceti Alpha is presumably a star in the Alpha Quadrant and inside the jurisdiction of the United Federation of Planets.
However Ceti Alpha VI is known to have undergone a catastrophic explosion which totally destroyed the planet.
The term "Alpha Ceti" is used in place of "Ceti Alpha" in the novelization of Star Trek: The Wrath of Khan, by Vonda McIntyre.

Their discovery, being published in Monthly Notices of the Royal Astronomical Society, suggests that even though Tau Ceti is the nearest Sun-like star, any planets that may orbit it would not support life as we know it due to the inevitable large number of devastating collisions.
Tau Ceti, only 12 light years away, is the nearest Sun-like star and is easily visible without a telescope.
We don't yet know whether there are any planets orbiting Tau Ceti, but if there are, it is likely that they will experience constant bombardment from asteroids of the kind that is believed to have wiped out the dinosaurs.

Tau Ceti is the destination of the Marathon, and Marathon 1 takes place with the colony ship in orbit around one of Tau Ceti's planets.
Tau Ceti, though one of the closest stars to the Sun, is one of the (apparently) dimmer stars that are visible without the aid of a telescope.
Tau Ceti is actually a rather Sunlike star, though somewhat smaller and cooler.

The astronomers' discovery, being published in Monthly Notices of the Royal Astronomical Society, suggests that even though Tau Ceti is the nearest Sun-like star, any planets that may orbit it would not support life as we know it due to the inevitable large number of devastating collisions.
Though the star Tau Ceti is similar to the Sun, any planets it has are unlikely to be havens for life, say a team of UK astronomers.
The similarity between Tau Ceti and our own sun ends with their comparable sizes and luminosities, explains Jane Greaves, Royal Astronomical Society Norman Lockyer Fellow and lead scientist: 'Tau Ceti has more than ten times the number of comets and asteroids that there are in our Solar System.

 Tau/Ceti
Tau is the more stable half of the pair, with Ceti being used for kernel and hardware hacking.
In general, you shouldn't run any job on tau that takes more several hours unless you need either the processors or memory uniquely available on tau.
If you want to run a job on tau that is going to take more than some small number of hours, you should send email to tau-forum warning people in advance, and be prepared to justify your need for tau.

The lower body consists of a lopsided square partly outlined by Theta Ceti at the north, Baten Kaitos at the east, and anchored by Tau Ceti, which lies right at the border of third and fourth magnitude (3.50).
Tau Ceti is one of the few stars visible to the naked eye that has a mass less than the Sun, only about 70 percent solar, which renders it a cool class G (G8) dwarf.
Alas, Tau Ceti seems to be all alone, no planet as yet discovered, though a 13th magnitude stellar "companion" does reside 90 seconds of arc away.

Tau Ceti, in the constellation Cetus, one of the closest stars to Sol, was long considered a good candidate for Earth-type planets.
Tau Ceti was accepted into the Federation, becoming the first extra-solar Federation territory, and a new wave of idealism and brotherhood of man develops.

You see, in 1967 there was a war in the Tau Ceti system between the inhabitants of Tau Ceti 4, and Tau Ceti 3.
Tau Ceti 3 was able to take advantage of the unstable geothermal activity in Tau Ceti 4's crust, and destroyed their planet.
Unfortunatly, due to the enourmous number of asteroids this created, Tau Ceti 3 had to build a series of Graviton beams to prevent their planet from being destroyed.

Tau Ceti is only 11.8 light years away.
This would be the most likely point of initial exploration by an ancient civilization such as the "Hav-musuv's," etc., who developed the art of interplanetary and interstellar travel hundreds or thousands of years before the "Internationals" on the surface of the planet were able to.
The map which was drawn by abductee Betty Hill from memory indicated, once it was lined up with contemporary star maps, that it connected with the Tau Ceti system as well as other systems.
