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?
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 would be brighter star than -1?
There is no such thing as a star with a magnitude brighter than -1. Negative magnitudes indicate brighter objects, with the most negative magnitudes corresponding to the brightest objects in the sky.
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.
Which star has the less absolute magnitude rigel or Sirius?
Sirius has a lower absolute magnitude than Rigel. Sirius is one of the brightest stars in the sky with an absolute magnitude of 1.42, while Rigel has an absolute magnitude of -8.1, making it much brighter than Sirius.
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.
How much brighter is a star with an apparent visual magnitude of 13.4 than a star with an apparent visual magnitude of 15.4?
A star with a visual magnitude of 13.4 is 10 times brighter than a star with a magnitude of 15.4, because each step in magnitude represents a factor of about 2.5 in brightness.
A star might be much brighter than it appears to be. This is called the star's absolute magnitude. The difference in apparent magnitude and absolute magnitude is due primarily to the star's -?

Which magnitude of star is brighter -5 or 2?
A magnitude of -5 is brighter than a magnitude of 2. The magnitude scale used in astronomy is inverted, meaning the lower the number, the brighter the object. So, a negative magnitude indicates a brighter star than a positive magnitude.
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 a third magnitude star 10 times brighter then a 4th magnitude star?
Absolutely. When speaking of the brightness you see from earth, you are speaking of apparent magnitude. When considering the type of star, it's composition, stage, age, size, distance, etc., a star is also assigned an absolute magnitude, so the ranking of the star if seen from similar distances reveals the truth about a star. 3.26 light years away is the assumed distance in ranking stars. A star many times farther away than a second star may appear much brighter than the second star which is much closer, based partially on the various factors mentioned above. The lower the value for a magnitude, the brighter, or more correctly, the more luminous, a star. Thus, a 3.4 is brighter than a 5.1, for example. Long ago the scale was originally an arbitrary ranking based on certain stars that were considered to be the brightest. Since then, stars even brighter have been identified, thus the need to use values even less than zero. Only a handful of stars fall below zero in apparent magnitude. So then it is not significant where in the sky (in what constellation) a star lies, the magnitude value determines the brightness.
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).
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.
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.
If star A is third magnitude and star B is fifth magnitude which is brighter and by what factor?
A 3rd magnitude star is brighter than a 5th magnitude star by a factor of 6.25.Each integer difference of magnitude represents a change in apparent brightness of 2.5 times. Hence, a 3rd magnitude star is 2.5 x 2.5 = 6.25 times brighter than a 5th magnitude star.(check related links)
