Yes, the diameter of a star can significantly affect its magnitude. Larger stars tend to have greater luminosity, which can lead to a brighter apparent magnitude when viewed from Earth. This is because a star's magnitude is influenced by both its intrinsic brightness (luminosity) and its distance from the observer. Therefore, a star with a larger diameter, assuming it is also hotter and more luminous, would generally appear brighter in the night sky.
What else can I help you with?
I am given the bolometric BC equals -1.46 and the visual magnitude V equals 4.33 of a star. how do you calculate the angular diameter?
The bolometric correction allows you to convert between visual and bolometric (total) magnitude - where the bolometric magnitude includes all radiation emitted by the star, not just visible light. It has nothing to do with the angular diameter.
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.
How does the magnitude of a star effect it's brightness?
The brightness of a star is not affected by its magnitude/size but is instead affected by the heat at which the star burns.

How diameter and absolute magnitude related?
the larger the mass of the star, the more luminous it is.
How does a star's temperature affect its absolute magnitude?
The absolute magnitude of a start will increase both:* If its surface temperature increases, and * If its diameter increases.
Why does a star look smaller than another star but is bigger than the other star?
Normally you would observe the star's brightness, not its apparent diameter.The star's apparent brightness ("apparent magnitude") depends on its real brightness ("absolute magnitude"), and on the distance. Similarly, the star's apparent angular diameter (which is VERY hard to measure) would depend on its actual diameter, and on the distance.
What is a star brightness called?
the brightness of a star is called it's magnitude
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 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 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.
