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).
What is the most luminous star?
Contenders are:- LBV 1806-20 - ~ 5,000,000 times brighter than the Sun. Pistol Star - ~ 1,000,000 times brighter than the Sun (Variable) Cygnus OB2-12 ~ 6,000,000 times brighter than the Sun HD 93129A ~ 5,500,000 times brighter than the Sun. Eta Carnae ~ 5,000,000 times brighter than the Sun.
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 much brighter is a supernova than a nova?
A supernova can be billions of times brighter than a nova. Novas occur on the surfaces of white dwarf stars and release energy comparable to millions of hydrogen bombs, while supernovae represent the explosion of an entire star and can briefly outshine entire galaxies.
Why does star Sirius appear brighter than star pollux?
Sirius appears brighter than Pollux because it is closer to Earth and is a more luminous star. Sirius is also a hot, blue star compared to Pollux, which is a cooler, orange giant star, further contributing to the difference in brightness.
What is a star that is millions of times brighter than the sun?
a Supergiant
What super is a star that is a million of times brighter than the sun?
super-giant star
What is a gigantigc explosion of a star millions or billions of times brighter than the star was?
A nova or supernova.
How many times brigther will a star be than an identical star that twice as faraway?
It is four times as brighter. It is four times as brighter.
How bright are star?
In absolute terms, some are brighter than our Sun - in some rare cases, millions of times brighter - while others are much less bright than our Sun.
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 many times brighter is a first magnitude star than a third magnitude?
2 magnitudes brighter means it's about 2.512 x 2.512 times brighter. So that's about 6.31 times brighter.
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).
How many times brighter will a star be than an identical star thats twice as far away?
4 times
How many times brighter will a star be than an identical star that is twice far away?
4 times as bright.
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 a brighter star?
A star that is brighter than another.
