Because of different luminosities and distances from Earth, Stars have brightness defined as either:
A) Apparent Magnitude - [See Link]. As seen from Earth
- The Sun
- Red Giant
- White Dwarf
- Nova (Depending on location)
B) Absolute Magnitude - [See Link]. Adjusted figures to a standard value.
- Nova
- The Sun
- Red Giant
- White Dwarf
NB: A Nova [See Link] is not really a star, just the process of a dying star.
What else can I help you with?
Are white dwarfs older than the sun?
Some white dwarfs are older than the sun, and some are not. More massive red dwarfs form from stars larger than the sun, which do not last as long.
How is it possible for white dwarfs of have a lower luminosity than the sun even though the sun is much cooler than the white dwarfs?
Because luminosity is a measure of brightness over distance. Also white dwarfs are a hundred times smaller than the Sun. Most white dwarfs are a long way away and thus are difficult to see.
Are white dwarfs brighter than supergiants?
Well, let me tell you, it's truly fascinating! White dwarfs are actually much smaller and cooler than supergiants, so they seem dimmer to our eyes. But despite their dimness, aren't they still shimmering orbs of beauty in the vast cosmos? Just remember, every star has its own brilliance and charm.
Why are stars brighter than the sun?
Most stars are dim red dwarfs which we cannot see. Most of the stars we can see actually ARE brighter than our sun. From our perspective, because we are so close to it, the sun appears big, the same reason a 100 watt light bulb in the same room appears brighter than stadium lights four miles away.
How many times brighter is the galaxy IRAS than the sun?
300,000,000,000,000 times brighter than the sun

How can dwarfs be so bright when they are smaller than the sun?
Dwarfs, such as white dwarfs or brown dwarfs, are small in size but can still be very bright because they have high temperatures that produce intense luminosity. The brightness of a dwarf is determined by its surface temperature, not its physical size. Therefore, even though dwarfs are smaller than the sun, their high temperatures allow them to emit significant amounts of light.
When was Brighter Than the Sun created?
Brighter Than the Sun was created on 2011-05-23.
How many times brighter is the galaxy IRAS than the sun?
300,000,000,000,000 times brighter than the sun
Is Mizar brighter than the Sun?
Yes, in "absolute magnitude", Mizar is much brighter than the Sun.
Is the sun brighter because it is closer than the other stars?
It is better to say that the sun appears brighter because it is closer. Some stars are actually brighter than the sun.
Why is the moon brighter than the sun?
it isn't the sun is 450000 times brighter than the moon! no..
How dense is the white dwarf to your sun?
A white dwarf is much denser than the Sun. White dwarfs have a typical density around 1 million times greater than the density of the Sun, resulting in a mass similar to the Sun's but packed into a much smaller volume.
Which is brighter larger stars or smaller stars?
Brightness is related to distance. However, from the same distance, an O class star is much much brighter than a M class star. As a comparison, an O class star would appear about 100,000 times brighter than our Sun, whereas a M class star could appear 0.0017 dimmer than our Sun, if the Sun was replaced with each star.
