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 magnitude of the star alioth?
what is the magnitude of the star Alioth in the constellation Ursa Major
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).
What is a star brightness called?
the brightness of a star is called it's magnitude
What is star's magnitude?
The magnitude is the brightness of the star.
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.
What is the magnitude of the complex number 8 plus 2i?
8.2462 (rounded)
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 star is called its magnitude?
The magnitude of a star means how bright it is.
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 is the distance between an eighth magnitude star and a 9th magnitude star?
The 8th magnitude star is about 2.5 times brighter.
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.
Is a third-magnitude star ten times as bright as a fourth-magnitude star?
No. The difference in 1 magnitude is the 5th root of 100 which is about 2.512. So a 3rd magnitude star is 2.512 times as bright as a 4th magnitude star.
