How would you calculate how much brighter a magnitude plus 4 star is than a magnitude plus 7 star?

The model for measuring the apparent magnitude (brightness from earth) of a star says that a magnitude 1 star will be 100 times brighter than a magnitude 6 star (just visible with the naked eye). This means that a magnitude 1 star is 2.512 times brighter than a magnitude 2 star, which is 2.512 times brighter than a magnitude 3 star. To jump two places up the scale, use 2.512 x 2.512 as a multiplier, i.e. mag 1 is 6.31 times brighter than magnitude 3 star. To jump three places use 2.512 x 2.512 x 2.512 (or 2.512 cubed) = 15.851. So a magnitude 4 star will be 15.85 times brighter than a magnitude 7 star. Working the other way, a magnitude 7 star will appear 6.3% as bright as a magnitude 4 star (1/15.85 and x 100 to get percentage).


Is the sun a first mag star?

no


What is a first magnitude star called?

The term magnitude is used to define the apparent brightness of an object from Earth. The scale has its origins in the Hellenistic practice of dividing stars, visible to the naked eye into six magnitudes.The brightest stars were said to be of first magnitudewhile the faintest were of sixth magnitude by visual perception.Each magnitude was considered to be twice the brightness of the following grade (a logarithmic scale).Nowadays there are more than six magnitudes and the use of negative values were introduced. So our Sun have an apparent magnitude of -26.73 whilst Uranus is 5.5See related for for information


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

What term is used to describe a star's brightness?

It is called Vmag. This is the visual magnitude of the object. Visual magnitude is a scale used by astronomers to measure the brightness of a star or other celestial object. Visual magnitude measures only the visible light from the object. The lower the V-MAG the brighter the star. You can go to http://seasky.org/pictures/sky7b14.html to learn more.
