The big stars have more hydrogen to burn and has much more surface area thats why it shines brighter.
Stars can be both cooler and brighter or hotter and dimmer than the Sun, depending on their size and age. Generally, larger and younger stars are hotter and brighter than the Sun, while smaller and older stars can be cooler and dimmer.
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.
some stars are smaller than sun remaining stars are bigger than sun.
It is better to say that the sun appears brighter because it is closer. Some stars are actually brighter than the sun.
The sun appears brighter than other stars because it is much closer to Earth, allowing us to receive a higher amount of its light and energy. Additionally, the sun is a relatively average-sized star, so its brightness is more prominent compared to much larger or smaller stars.
Stars with larger masses have stronger gravity; this results in more pressure; which in turn makes the star hotter. As a result of the higher temperature, they will shine brighter, and burn their fuel much faster.
Well,planets do not have any light of their own so they are definitely not brighter and yes there may be some stars smaller than the planets but most of the stars are bigger than the planets . But on the whole the Space is not that much explored so that we can get any cumulative answer.

The Sun is bigger than some stars and smaller than others. It is brighter than some stars and dimmer than others. Relative to the Earth it is much closer than all other stars.
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.
The smaller numbers indicate brighter stars. Also, a negative magnitude is even brighter than zero magnitude.
No. Stars generate their own light, and are far more massive than any comet. Comets don't shine at all; they merely reflect the light of the Sun. From our perspective here on Earth, some comets appear to be brighter than stars, but only because the comets are here in THIS solar system, relatively nearby, while stars are many light-years away.
Quasars A+
In absolute terms larger (more massive) stars shine more brightly than less massive ones. In relative terms (as seen from Earth) more distant stars appear dimmer than closer ones.
Because they are closer or actually brighter.
Tomorrow is going to be a BRIGHTER day. The sun is BRIGHTER today then yesterday. Some day I will shine BRIGHTER than the sun.
