Stars are more brighter than other stars because they have different characteristics that affect their luminosity. Luminosity is the amount of energy that a star emits per unit of time. It depends on the star's size, temperature, and distance from the observer.
Some of the factors that make stars more brighter than other stars are:
Size: Larger stars have more surface area and can emit more light than smaller stars.
Temperature: Hotter stars have higher energy and can emit more light than cooler stars.
Distance: Closer stars appear brighter than farther stars because their light has less space to travel and lose intensity.

Why is the north star so much brighter than other stars?
The north star, otherwise know as Polaris, is brighter than many other stars because it is much closer and perhaps larger than many other stars.
Is a hot star blue and fainter or blue and brighter?
It is brighter because it is emitting more gasses at a faster rate than other sized main sequence stars.
Why does pole star appear larger and brighter than other stars?
It doesn't. A lot of stars seem larger and brighter than it. In fact, Polaris is the 49th-brightest star in the sky. To us, it is not a particularly bright star. It is important because it seems to be still as other stars rotate around it.
Why do some stars look brighter than others?
Stars look brighter than others due to factors such as their size, temperature, and distance from Earth. A larger and hotter star will appear brighter, as will a star that is closer to us. The brightness of a star as seen from Earth is measured by its apparent magnitude.
The sun looks larger and brighter because it is what star to the earth?
The sun is the closest star to Earth, which is why it appears larger and brighter in our sky compared to other stars. Its proximity allows for more direct sunlight to reach us, making it appear more prominent.
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.
Why can one star be more brighter than another?
One star can be brighter than another due to factors such as its size, temperature, and distance from Earth. Larger and hotter stars tend to be brighter, while stars that are closer to Earth appear brighter in the sky. Additionally, the composition of a star's atmosphere and any surrounding objects can also impact its brightness.
Why does a medium sized stars appear brighter than the others?
The Sun is the closest star to Earth, so it appears much brighter than other, more distant stars. The Sun is eight light-MINUTES away from the Earth. The NEAREST other star is 4.2 light years away (Proxima Centauri).
Is sirius larger and has more energy than any other star in the galaxy?
No. Sirius is a fairly large star, but it is nothing extraordinary. It only appears brighter than the other stars in the night sky because it is one of the closest stars to us.
How does brigthness vary from the size of the star?
Brighter stars are typically larger in size because they have more surface area to emit light and heat. The luminosity of a star depends on its size, with larger stars generally being brighter than smaller stars. However, other factors such as temperature and distance also play a role in determining a star's brightness.
Is the sun brighter than a star?
Yes, the sun s brighter than most stars, but it is dimmer than most of the stars we can see with our naked eye.
Why does the sun appear brighter than other stars from Earth?
The Sun is the closest star to Earth, so it appears much brighter than other, more distant stars.The Sun is eight light-MINUTES away from the Earth. The NEAREST other star is 250,000 times further away.
