Magnitudes of stars start in the negative, so the brightest star from Earth is of course the Sun, so it has an apparent magnitude of -26.74 (Note negative), whereas Polaris (The North Star) has an apparent magnitude of +1.97
See related question for differences between apparent and absolute magnitude.

The brighter an object is, the lower its magnitude.
The sun's apparent visual magnitude is -26 (negative). The largest optical telescopes now in use,
using long exposures, can record objects in the neighborhood of magnitude +26 (positive).

Which magnitude would be associated with the brighter star?
The greater a star's magnitude, the brighter it appears in the sky. Magnitude is a scale of apparent brightness as seen from Earth and says nothing about how large a star actually is or how much energy it is radiating. A small star that is closer may have a greater magnitude, as seen from Earth, than a large, active star that is much further away.
What is the difference between a twelfth magnitude and fifteenth magnitude star?
Three magnitudes, and the 12th magnitude star is the brighter star. Mathematically it means the brightness difference is about: 2.512 x 2.512 x 2.512. That's about 15.85 times brighter.
What is brighter a second or a third magnitude star?
2nd magnitude is brighter than 3rd. 6th magnitude is the dimmest that can be seen with the naked eye; many more can be seen in binoculars, telescopes etc.
Is apparent magnitude an indicator of a star's temperature?
The apparent magnitude of a star is a measure of its brightness as seen from Earth, the lower the number, the brighter a star is. Ex. a star that has an apparent magnitude of -20 is WAY brighter from Earth than a star with a apparent magnitude of 20.
How will a star bright if it was near the sun?
A star near the Sun might be brighter or dimmer, it depends on how big it is. Each star has an absolute magnitude and if you find out a star's absolute magnitude, and then subtract 31.4, that would be its visual magnitude at the Sun's distance from us.
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.
Which star is brighter one with magnitude of 6.3 or one whit a magnitude of 14?
The lower the magnitude, the brighter it appears.
Which magnitude would be associated with the brighter star?
The greater a star's magnitude, the brighter it appears in the sky. Magnitude is a scale of apparent brightness as seen from Earth and says nothing about how large a star actually is or how much energy it is radiating. A small star that is closer may have a greater magnitude, as seen from Earth, than a large, active star that is much further away.
What is the distance between an eighth magnitude star and a 9th magnitude star?
The 8th magnitude star is about 2.5 times brighter.
Which star is brighter a star with a magnitude of 3.2 or 4.6?
A star with an apparent visual magnitude of 3.2 appears 1.4 magnitudes brighter than another one whose apparent visual magnitude is 4.6 .
Which star is brighter one with a 6.3 magnitude or one with a magnitude of 1.4?
The smaller numbers indicate brighter stars. Also, a negative magnitude is even brighter than zero magnitude.
Which magnitude of star is brighter -5 or 2?
Negative magnitudes are always brighter. Our Sun has an apparent magnitude of -26.3
What stars are visible from earth?
a star with apparent magnitude of 6 or less, the lesser the magnitude the brighter the star
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 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).
Magnitude of the schedar star the schedar star?
The magnitude of the Schedar star in Cassiopeia is -1.985. Remember Negative stars are brighter.
Name for How bright a star is from the earth?
The brightness of a star is called visual magnitude. The lower the visual magnitude is the brighter the star is.
