It is a triple star system. Therefore every single star has different luminosity.
However, as a whole the system is seen from earth at an appereant magnitude of 3.47, which means only %6 luminosity of the star vega.
Adding to what Hilmas Zonneveld posted, Cetus is another constellation where Alpha (Menkar) is not the brightest star. Menacer is mag 2.4. The brightest is Beta Ceti, Deneb Kaitos or Diphda. Several stars are known as Deneb or have that word in their names. Deneb means 'tail'.
Tau Ceti - album - was created in 2002.

Tau Ceti - video game - happened in 1985.

'Ceti Alpha V' is the planet upon which Khan was marooned .
I was enthralled by the luminosity of the deep water jellyfish.

The luminosity of a black body is given by the Stefan-Boltzmann formula:: Stefan-Boltzmann constant;A: Surface area of the black bodyT: Temperature in Kelvin1st: The relevant surface area for the Hawking radiation is the surface area of a sphere with the radius of the Schwarzschild radius, because that's where the radiation originates:A sphereBy Team C007571, ThinkQuest 2000.We can substitute this in the formula for the luminosity:2nd: We have already calculated the temperature of a black hole:Putting this into the formula for the luminosity we get:Some example calculationsA black hole the mass of the EarthThe luminosity of a black hole with the mass of the Earth equals:Black hole in "The Hole Man"The luminosity of the black hole in "The Hole Man":35.7 gigawatts of hard gamma-radiation would certainly be absolutely deadly!Black hole with the Luminosity of the sunThe SunCourtesy of NASA.Nix NASA Image EechangeGRC Number: C-82-6709Date Archived: 11/22/1982How heavy will be a black hole with the luminosity of the sun?A black hole of only 961kg of mass would have the same luminosity as the sun. And it would only be across! (diameter of the Schwarzschild radius). This black hole wouldn't be visible though, because it emits deadly gamma-radiation.
