How many times brighter is Capella than the sun?
Rigel has a luminosity of 66,000 times greater than our Sun.However, in apparent magnitude (Brightness) it has a magnitude of 0.18 whereas the Sun is -26.73.
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).
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 betelgeuse than aldebaran?
Betelgeuse is approximately 100,000 times brighter than Aldebaran. This significant difference in brightness is primarily due to Betelgeuse's status as a red supergiant star, which has a much higher luminosity compared to Aldebaran, a red giant star. Factors such as size and temperature contribute to this disparity in their brightness as seen from Earth.
How many times brighter is a cepheid variable of absolute magniture -3 than a white dwarf of absolute magnitude of 7?
That is a difference of ten magitudes so the factor in brightness is 10,000.
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 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.
What is bigger an Andromeda galaxy or the sun?
A galaxy is many many times larger than one sun.
How many times brighter is Capella than the sun?
Rigel has a luminosity of 66,000 times greater than our Sun.However, in apparent magnitude (Brightness) it has a magnitude of 0.18 whereas the Sun is -26.73.
How many times will the solar system fit into the galaxy?
Billions of times
How many times do you have to fail a galaxy for Rosalina to appear in Super Mario Galaxy 2?
7 times you must lose a life in the galaxy and then the super guide engages.
What is the brighter than stars?
There are many stars that are brighter than the sun. Deneb shines the brightest in the constellation Cygnus and is much farther from Earth than most of the other stars you see. Deneb is about 100,000 times brighter than the Sun. HR 5171, has a diameter 1,300 times the sun and is a million times brighter than the sun. R136a1 weighs up to 300 times the mass of the Sun and is close to 10 million times brighter than the sun.
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.
Is the sun the only star known in this galaxy?
No, the sun is only one minor rather small star among the billions of stars (many much larger and brighter than the sun) that make up the Milky Way galaxy.
How much brighter is a quasar than the sun?
Quasars are among the brightest objects in the universe and are intrinsically far, far brighter than stars, though the one which appears brightest to us on Earth (3C 273, a quasar in the constellation of Virgo) is so far away (about two and a half billion light years) that it cannot be seen without a telescope. 3C 273 is actually two trillion times as bright as the Sun and is in fact about a hundred times brighter than the entire Milky Way galaxy. We do think that quasars involve supermassive black holes, but what we see is not the black hole itself (which is, well, black and therefore invisible) but its accretion disc.
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).
