How much brighter will a star of 1st magnitude appear compared with one of 9th magnitude?
A star of 1st magnitude appears approximately 100 times brighter than a star of 9th magnitude. The brightness scale is logarithmic, with each whole number change in magnitude corresponding to a brightness difference of about 2.5 times. Therefore, the difference between 1st and 9th magnitude is 8 steps, resulting in a brightness factor of about (2.5^8), which equals roughly 3900 times, indicating that the 1st magnitude star is significantly brighter.
How much brighter is a magnitude 2 star than a magnitude 4 star?
A magnitude 2 star is 2.5 times brighter than a magnitude 4 star because each difference in magnitude corresponds to a difference in brightness of approximately 2.5 times.
Is a high magnitude star more dense than a low magnitude star?
Magnitude is a measure of brightness, there is no relationship with density.
What is difference in a star's apparent magnitude and absolute magnitude caused by?
How far away the star is.
What is the difference between a twelfth magnitude and fifteenth magnitude star?
The main difference is brightness: a twelfth magnitude star is brighter than a fifteenth magnitude star. Magnitude is a logarithmic scale, so each step in magnitude represents a difference in brightness of about 2.5 times. This means a twelfth magnitude star is approximately 12.5 times brighter than a fifteenth magnitude star.
What is the name of the brightest star in Sagittarius with a magnitude of plus?
Epsilon Sagittarii (Kaus Australis) is the brightest star in the constellation Sagittarius with an apparent visual magnitude of +1.8.
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).
How much brighter will a star of 1st magnitude appear compared with one of 9th magnitude?
A star of 1st magnitude appears approximately 100 times brighter than a star of 9th magnitude. The brightness scale is logarithmic, with each whole number change in magnitude corresponding to a brightness difference of about 2.5 times. Therefore, the difference between 1st and 9th magnitude is 8 steps, resulting in a brightness factor of about (2.5^8), which equals roughly 3900 times, indicating that the 1st magnitude star is significantly brighter.

What is star's magnitude?
The magnitude is the brightness of the star.
What part of a star is called magnitude?
Magnitude refers to the brightness of a star. There are two main types: apparent magnitude, which is how bright a star appears from Earth, and absolute magnitude, which measures a star's intrinsic brightness.
What is the magnitude of a star as it appears in the sky called?
The Polar star is the star that is magnitude. This is a Luminosity star.
What magnitude indicates the brightest star -1 0 -0.11 plus 4?
It would be -1 the further Negative you go the brighter the star.
What star is called its magnitude?
The magnitude of a star means how bright it is.
What is the distance between an eighth magnitude star and a 9th magnitude star?
The 8th magnitude star is about 2.5 times brighter.
