The sun is extremely bright because it is a nuclear fusion machine that is constantly "on" and generating lots of energy. Additionally, the earth, from which we view the sun, is not so far away that a great quantity of light can't reach earth from our local star.
The Sun's intrinsic brightness or luminosity can be defined on two scales.
The Suns Apparent magnitude is -26.74 (Yes negative) whilst it's absolute magnitude is 4.83.
This means that the Sun is around 450,000 times brighter than the moon (an apparent magnitude of -12) , but from Neptune the Sun is -20. So the Sun is brighter on Neptune than the Moon is from Earth.
I depends on which star it is, the brightness of light is measured in 'solar mass', for example, the sun has 1 solar mass, the blue-white supergiant has 150 solar mass and the red giant has less then 5 solar mass.
The bigger the number, the brighter the star.
When four hydrogen atoms fuse together to form helium, a tiny bit of each atom turns into energy. The amount of energy created is predicted by Albert Einstein's famous equation: E = mc2. You don't need to be an Einstein to understand this equation's meaning: A small amount of stuff can turn into a huge amount of energy, under the hot conditions inside a star.
Some of them can be millions of times as bright as our Sun.

The sun consists of millions of different gases all reacting together. The result is a constant explosion of heat and a temperature far greater than an average fire on earth. These explosions makes the sun look so bright.
The main reason that the sun appears so large and bright to us is that we're so
close to it. The next nearest star is about 270 thousand times farther away than
the sun is, and all the others are even farther than that.
The reason the sun is hot is because of nuclear fusion. The reason the sun
appears so bright to us is because it's so close to us. About half of all the
stars you see in the sky at night are just as bright, or even brighter, than
the sun, but they're all much farther away from us.
i hope u know that the sun was the nearest star to the earth. and that is one of the reasons why is the sun is so bright. it is also made up of hot gasses. other trivia about the sun. it is just a medium-sized star. it looks like a really big star because it's near to the earth. another trivia is that the sun's features are solar flares, sun's corona, ____. the color of the sun is yellow. stars have different colors. it is classified according to their temperature.
In general, Jupiter appears brightest when it is in opposition. Your latitude may also affect the apparent brightness: if, for example, you live in the northern hemisphere, and Jupiter happens to be too far south, atmospheric extinction may reduce the apparent brightness.
From the vicinity of Jupiter, it would appear much smaller than from Earth, and about 1/27th as bright, like an extremely bright star.
Look outside your window.
It is jupiter.. Its gasses are reflecting the sun..
As of January 2018, that is probably the planet Jupiter.
the sun is too bright it will burn your eyes bad
No. It wouldn't be as big or as bright as it is here, but you can still see it
From the vicinity of Jupiter, it would appear much smaller than from Earth, and about 1/27th as bright, like an extremely bright star.
Callisto is a moon of Jupiter, so on average it is the same distance from the Sun as Jupiter is. You can easily look up the distance from the Sun to Jupiter.
Look outside your window.
Look at the sun or a bright light.
It is jupiter.. Its gasses are reflecting the sun..
As of January 2018, that is probably the planet Jupiter.
The sun would look much smaller than it does from Earth but still bright.
the sun is too bright it will burn your eyes bad
From the distance of Pluto, the Sun would look like a very bright star.
4 times brighter.
Yes. Look at that bright yellow ball in the sky. It is the sun.
