Our Sun is the brightest star of course, but presuming you discount that, the next brightest are:Sirius, Canopus, Alpha Centauri, Arcturus, Vega, Capella, Rigel and Procyon.

What else can I help you with?
Are the brightest stars low or high magnitude?
The brightest stars have a low magnitude. Magnitude is measured on a logarithmic scale where lower numbers indicate brighter objects. The brightest star in the night sky, Sirius, has a magnitude of -1.46.
The brightest stars have apparent magnitudes that are?
The brightest stars have apparent magnitudes that are lower, indicating they appear brighter in the sky. The apparent magnitude scale is inverted, with lower values representing brighter objects and higher values representing dimmer objects. Bright stars typically have apparent magnitudes between -1 to 1.
What is a second magnitude star?
A second magnitude star is a star that is relatively bright in the night sky, typically with an apparent visual magnitude between 1.5 and 2.5. These stars are easily visible to the naked eye and are brighter than third magnitude stars but dimmer than first magnitude stars.
Is a third magnitude star 10 times brighter then a 4th magnitude star?
Absolutely. When speaking of the brightness you see from earth, you are speaking of apparent magnitude. When considering the type of star, it's composition, stage, age, size, distance, etc., a star is also assigned an absolute magnitude, so the ranking of the star if seen from similar distances reveals the truth about a star. 3.26 light years away is the assumed distance in ranking stars. A star many times farther away than a second star may appear much brighter than the second star which is much closer, based partially on the various factors mentioned above. The lower the value for a magnitude, the brighter, or more correctly, the more luminous, a star. Thus, a 3.4 is brighter than a 5.1, for example. Long ago the scale was originally an arbitrary ranking based on certain stars that were considered to be the brightest. Since then, stars even brighter have been identified, thus the need to use values even less than zero. Only a handful of stars fall below zero in apparent magnitude. So then it is not significant where in the sky (in what constellation) a star lies, the magnitude value determines the brightness.
If star A is third magnitude and star B is fifth magnitude which is brighter and by what factor?
A 3rd magnitude star is brighter than a 5th magnitude star by a factor of 6.25.Each integer difference of magnitude represents a change in apparent brightness of 2.5 times. Hence, a 3rd magnitude star is 2.5 x 2.5 = 6.25 times brighter than a 5th magnitude star.(check related links)
Star A is a first magnitude star. Star B is a sixth magnitude star. Which star is brighter and by how much?
A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.A magnitude 1 star is 100 times brighter than a magnitude 6 star.

The brightness of stars as they appear from Earth is measured by magnitude?
Stars are measured in brilliance called magnitude. The faintest stars visible to the naked eye are mag.6. Brighter ones are mag. 1 or 2, the even brighter stars have negative magnitude. So its like a number line in math: Brighter Fainter -6_-5_-4_-3_-2_-1__0__1_2_3_4_5_6
The brightest stars have apparent magnitudes that are?
The brightest stars have apparent magnitudes that are lower, indicating they appear brighter in the sky. The apparent magnitude scale is inverted, with lower values representing brighter objects and higher values representing dimmer objects. Bright stars typically have apparent magnitudes between -1 to 1.
Is a star with magnitude -1 the brightest?
Lower magnitude numbers are brighter; negative numbers represent brighter objects than positive numbers.
What is a second magnitude star?
A second magnitude star is a star that is relatively bright in the night sky, typically with an apparent visual magnitude between 1.5 and 2.5. These stars are easily visible to the naked eye and are brighter than third magnitude stars but dimmer than first magnitude stars.

What things must an astronomer measure to calculate a star's absolute brightness?
Telescopes, combined with spectroscopy are used for the colors. The apparent brightness can be measured using a telescope with a special "CCD camera". To measure the "real" brightness ("absolute magnitude") you also need to be able to work out the distance to the star.
What are the eight conspicuous stars magnitude 1?
The question is, I think about "apparent magnitude". The question is hard to answer precisely, because there aren't eight stars of magnitude 1 exactly. There is the expression "stars of the first magnitude" which is the 21 brightest stars (in apparent magnitude). Our Sun is not included. Anyway, here is that list starting with Sirius, the brightest (magnitude -1.46) down to Regulus (magnitude +1.36) : Sirius Canopus Arcturus Alpha Centauri Vega Capella Rigel Procyon Betelgeuse Achernar Hadar Altair Acrux (Alpha Crucis) Aldebaren Spica Antares Formalhaut Pollux Deneb Becrux (Beta Crucis) Regulus.

A 3rd magnitude star is brighter than a 5th magnitude star by a factor of 6.25.Each integer difference of magnitude represents a change in apparent brightness of 2.5 times. Hence, a 3rd magnitude star is 2.5 x 2.5 = 6.25 times brighter than a 5th magnitude star.(check related links)
How many times brighter is a magnitude 1 star than a magnitude 2 star?
Good, a nice question with a definite answer. The magnitude1 star is 2.512 times brighter (near enough).
How is stars brightness measured from earth?
Astronomers use a special term to talk about the brightness of stars. The term is "magnitude". The magnitude scale was invented by the ancient Greeksaround 150 B.C. The Greeks put the stars they could see into six groups. They put the brightest stars into group 1, and called them magnitude 1 stars. Stars that they could barely see were put into group 6. So, in the magnitude scale, bright stars have lower numbers.
