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.

Why is the sun appear brighter than alpha centauri b?
Our Sun appears brighter than Alpha Centauri B because of its proximity to our point of view. We are much closer to our Sun then any other star which means that our Sun will be much brighter then everything else in the sky.
What 2 objects are brighter in the sky than Venus?
The Sun and the Moon are the only celestial objects that appear brighter in the sky than Venus.
Why does the sun appear brighter than a star?
The Sun is much, much closer to the Earth than any other star - eight light minutes vs. four light years for the next nearest star.
Why does the sun shines brightly than other stars?
The Sun appears brighter than most other stars because it is much closer to Earth. Its proximity makes it seem brighter and more intense. Additionally, the Sun's luminosity is higher than many other stars due to its size and age, contributing to its apparent brightness from our perspective on Earth.
The surface temperature of the star Rigel is about 15000celiusThe sun has a temperature of about 6000celius Why does the sun appear so much brighter?
The brightness of a star depends not just on its surface temperature, but also on its size and distance from Earth. While Rigel is hotter than the Sun, it is also a much larger and more luminous star. Therefore, even though the Sun is cooler than Rigel, it appears brighter to us because it is much closer and has a larger luminosity due to its size.
Is Mizar brighter than the Sun?
Yes, in "absolute magnitude", Mizar is much brighter than the Sun.
How much brighter is quasar than the sun?
Immeasurably more brilliant. A quasar (quasi-stellar radio source) is as bright as some entire GALAXIES. We believe that a quasar is an actively-expanding super-massive black hole, and that these black holes may exist in the centers of many or most large galaxies - including our own Milky Way.
Is a welder brighter than the sun?
No, a welder is not brighter than the sun. The sun is a star and emits much more light and energy than any welding process.
Why is the moon brighter than the sun?

Why is the sun appear brighter than alpha centauri b?

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 much brighter is rigel than the sun?
Rigel is approximately 120,000 times brighter than the Sun. This high luminosity is due to Rigel's much larger size and higher temperature compared to the Sun.
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?

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.
