It is 470 ly (light years).
The reference that astronomers use to compare the luminosity of other stars is the sun's luminosity. The luminosity is denoted in multiples of the sun's luminosity. For example, the luminosity of the star Sirius is 25 times the luminosity of the sun.
Sirius is actually a binary star system. Sirius A has a luminosity of 25.4 solar luminosity Sirius B has a luminosity of 0.026 solar luminosity See related link for more information.
the luminosity of Vega is 3.8
Cepheids have a certain relationship between their period, and their absolute luminosity. Thus, their absolute luminosity can be determined. Comparing this with their apparent luminosity allows us to calculate their distance. Cepheids have a certain relationship between their period, and their absolute luminosity.

A star's luminosity is measured according to the relevance to the sun. Basically for example, if a star is 8,300 degrees Celsius and has a luminosity of 0.001; the luminosity is compared to the sun.
The absolute luminosity is about 3.839×1026 W, or 3.839×1033 erg/second. The comparative luminosity of an astronomical object is based on the Sun, so it has a relative luminosity of 1.
I was enthralled by the luminosity of the deep water jellyfish.
Polaris has a luminosity of 2,200 solar luminosities.
Michael Emerson is in the Luminosity commercial.
Rigel has a luminosity of 117,490 solar luminosities.
To determine a star's luminosity is from size and temperature.
Deneb has a luminosity (apparent magnitude) of 1.25. However, in bolometric luminosity (solar units) Deneb is 54,000, whereas our Sun is 1.
it's luminosity is 10 and it's color is white
The stars shone with a luminosity reminiscent of diamonds on black velvet .
Generally, the luminosity of red dwarfs are very low. The largest red dwarf known (Lacaille 8760) has a luminosity 10% of our own Sun, whereas the coolest has a luminosity 1/10,000th that of our Sun.
A solar luminosity is equal to the current luminosity of the Sun, which is 3.839 × 1026 W, or 3.839 × 1033 erg/s. So dividing one solar luminosity with the Suns luminosity gives 1. Also it is a lot easier talking about a luminosity of 1 rather than 3.838 x 1026 W, the same way astronomers use 1 AU to mean 150,000,000km.
Betelgeuse has about 140,000 times the luminosity of our sun or about 5.37×1031 watts.
The luminosity of this star is 170 times the solar luminosity . Arcturus star is the brightest star in the constellation Bootes and fourth brightest star in he night sky .
The luminosity depends on what stage of its life cycle the star is in. Also, the apparent luminosity depends on the distance from earth.
Luminosity is the total amount of energy emitted by a star per second.
A star's luminosity depends on two characteristics: size and temperature of star.
The main star in the Polaris system has a luminosity which is 2500 times that of the Sun.
Both the absorption and the luminosity of a blackbody in equilibrium increase in magnitude with increasing temperature, and the spectral distribution of the luminosity increases in frequency (decreases in wavelength).
No. Apparent magnitude (or luminosity) means how bright a star (or other object) looks to us; absolute magnitude (or luminosity) refers to how bright it really is.
Luminosity is really the same as apparent magnitude. See related questions.
Luminosity - 2012 was released on: USA: 31 December 2012 (limited)
The cast of Luminosity - 2013 includes: Avery Hatch as Agatha
They are only rare at some luminosity levels. The sun is luminosity 1. In the range of luminosity 10 to 100, O and B class stars are quite common.
Yes. Around 76% of the stars are low luminosity stars.
..... something wrong with it. Generally luminosity is related to temperature.
Apparent Brightness = luminosity/4(pi)x(distance)^2
What star has the surface temperature of approximately 9000 k and luminosity 1 to 20 times greater then the suns luminosity?
absolute magnitude is how bright the star actually is and luminosity is how bright it looks.
What happens to the surface temperature and luminosity when gravity first assembles a protostar from a collapsing cloud?
Its surface temperature and luminosity increase.
Blue stars are very hot stars and so usually have high luminosity.
If the binary stars were of too high luminosity it would be impossible to distinguish the two through vision alone. Therefore most visual binary stars are of low luminosity.
A star's luminosity is basically how much light it gives out per second. How bright the star appears to us also depends on the star's distance from Earth. So, a particular star can appear dimmer than another star even though it really has a greater luminosity.
In astronomy, Luminosity is the amount of energy a body radiates per unit time. The luminosity of stars is measured in two forms: apparent (counting visible light only) and bolometric (total radiant energy); a bolometer is an instrument that measures radiant energy over a wide band by absorption and measurement of heating. When not qualified, luminosity means bolometric luminosity, which is measured in the SI units watts, or in terms of solar luminosities, ; that… Read More
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.
About 11 times the luminosity of our Sun which is about 4 x 10^33 (to the power of 33) erg/sec.
On a logarithmic scale for luminosity, it is quite close to a negative linear relationship.
Sirius has a luminosity of: 25.4 while Rigel has a luminosity of: 66,000 Making Rigel brighter than Sirius.
Which statement describes the general relationship between temperature and luminosity of main sequence stars?
as surface temperature increases, luminosity increases
1.Luminosity is the amount of light emitted from a certain light source whereas brightness is the amount of light manifested or received. 2.The area of illumination is inversely proportional to brightness whereas luminosity isn't. 3.Brightness is usually expressed in 'Lumens' whereas luminosity is expressed in candela per square meter (photometry).
Several ways. By its size, orientation, colour, luminosity are some possible criteria. Several ways. By its size, orientation, colour, luminosity are some possible criteria. Several ways.
