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.
What else can I help you with?
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.
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.
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 magnitude of star can the human eye see?
The human eye can typically see stars with a magnitude of about +6 or brighter on the magnitude scale. Brighter magnitudes correspond to dimmer stars.
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.
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 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.
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.
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.
What is the distance between an eighth magnitude star and a 9th magnitude star?
The 8th magnitude star is about 2.5 times brighter.
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.
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.
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.
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 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).
